    Also, this case is a bit different than an "average" aquarium, because both the biofiltration and the oxygenation is or could be handled pretty well by the plant population. Especially with the CO2 injection, the plants (well, the cabomba anyway) seems to grow almost before my eyes. If only my aldrovanda would do that. [img]http://www.**********.com/iB_html/non-cgi/emoticons/sad.gif[/img] It's growing longer, but the rosettes are much smaller than they were before, and i'm not sure why. Anyway, i tend to do around 30% water changes when i do change. It's really a pain to get out and put in much more water than that with all the plants around.

    One thing that has changed lately is that the algae that is growing is red, instead of the green spot that usually stains the glass in a week or two. I know somewhere on the krib somebody describes which algae grows in response to which nutrient pressures, so perhaps i'll go check it out.

    Bobby, do you think that the other fish in the tank are a factor in the kribs not getting together? It seems like often when the female is doing her little dance, the male notices a rainbow or platy or puffer hovering in his territory, and rushes off to run the miscreant out. I haven't the experience to know if that's typical or if that's preventing him from focusing on the female.

    Also, do you know what role photoperiod plays, if any?

    Thanks

    Hi D muscipula,

    With the CO2 injection do you test for CO2 levels? If not, see if you can pick up a little tester by Eheim or Dupla that goes inside the tank and stays there. It uses a reagent that changes color to show CO2 levels and they work great. They really tell you how well your CO2 is doing. [img]http://www.**********.com/iB_html/non-cgi/emoticons/biggrin.gif[/img] I forgot to say, I have tons of plants in all my tanks but they are all in clay pots or mounted on driftwood or floating. I keep bare bottom tanks, painted black on the outside as it makes them easier to clean. All my tanks look like CP terrariums [img]http://www.**********.com/iB_html/non-cgi/emoticons/wow.gif[/img] [img]http://www.**********.com/iB_html/non-cgi/emoticons/tounge.gif[/img] or underwater greenhouses full of potted plants.
    The other fish being there will help form the pair bonding. It's natural that he chases them out of his territory. It will also stimulate the kribs later to protect the eggs and fry -- they can be #### on wheels at that time [img]http://www.**********.com/iB_html/non-cgi/emoticons/biggrin.gif[/img] . The female controls the breeding. When she is fat enough, dances long enough and insists "let's go", he will get the idea -- that's why conditioning her is so important [img]http://www.**********.com/iB_html/non-cgi/emoticons/rolleyes.gif[/img] .
    Puffers [img]http://www.**********.com/iB_html/non-cgi/emoticons/wow.gif[/img] [img]http://www.**********.com/iB_html/non-cgi/emoticons/wow.gif[/img] . Now we know where those baby platies are going [img]http://www.**********.com/iB_html/non-cgi/emoticons/sad.gif[/img] . They would also pick off the krib fry
    Kribs really live in a basically 12/12 hour photo period. It's not crucial. When they breed you might want to leave a little desk lamp on nearby to simulate dim moon and star light. It helps the adults herd the "cats". They will even put them to bed when they know it's "lights out". How many watts of light are on the tank and what size is the tank?
    Is this red algae bushy red algae or flat little red circles on the glass and rocks?

    Spectabilis73,

    I didn't mean to imply you were wrong and I was right. Please don't be offended. I was just trying to explain that there was alot of experience behind what I was saying so that it didn't sound like a wild untested idea [img]http://www.**********.com/iB_html/non-cgi/emoticons/smile.gif[/img]. Some people change alot of water each week and others change less. Both can work just fine. I just have reasons for doing large changes. It helps the fry to grow large and healthy. It helps keep algae down. Most fish seem to enjoy it -- but not all. It's a great disease preventative. And it stimulates breeding. (Although not changing water and a bit of neglect is sometimes the answer [img]http://www.**********.com/iB_html/non-cgi/emoticons/tounge.gif[/img] ).[/QUOTE]
    Sorry, I guess I looked at it wrong... [img]http://www.**********.com/iB_html/non-cgi/emoticons/confused.gif[/img]
    everyone has their own opinions and ways of doing things, I once tried to do a 75% water change, I lost half of my guppies... (this is when I first started growing fish [img]http://www.**********.com/iB_html/non-cgi/emoticons/wink.gif[/img] [img]http://www.**********.com/iB_html/non-cgi/emoticons/rolleyes.gif[/img] ) That's why I prefer not to do such large water changes, but for other people it works just fine... [img]http://www.**********.com/iB_html/non-cgi/emoticons/confused.gif[/img]
    With my 16 inch pacus I loose about 15 gallons a week through evaporation, and I change another 20% a week thorugh gravel cleaning. I'm thinking of selling them, It costs me 20 dollars a month to feed them, and I think it's easyer just to care for cichlids [img]http://www.**********.com/iB_html/non-cgi/emoticons/tounge.gif[/img] [img]http://www.**********.com/iB_html/non-cgi/emoticons/wink.gif[/img]
    That reminds me, I can't get my convict cichlids to breed, maybe you could help me? [img]http://www.**********.com/iB_html/non-cgi/emoticons/biggrin.gif[/img] [img]http://www.**********.com/iB_html/non-cgi/emoticons/smile.gif[/img]

    Hi Spectabilis73,

    I'm glad you understood [img]http://www.**********.com/iB_html/non-cgi/emoticons/tounge.gif[/img] . I'd hate to offend someone here my first week [img]http://www.**********.com/iB_html/non-cgi/emoticons/rolleyes.gif[/img] .
    I read your convict journal. My guess on your difficulty might be that they are a bit young. Convicts can breed at 1 and 1/2 inches but larger is a surer bet. I would focus on feeding them well. Have you ever looked at a site called <brineshrimpdirect.com>? They sell some great food products, especially a large package of freeze dried bloodworms at a cheap price. You can get 4 times the amount of bloodworms that come in the large (.71oz) Tetra foods can for the price of one large Tetra foods can! The worms are bigger too.
    I would give the convicts as much live food as you can, maybe 3 or 4 small feedings a day. They would love finely chopped (frozen first) earthworms, mosquito larvae, pin head cricketts, plus frozen brine shrimp and bloodworms. Hikari pellets are very good. I like the micropellets. They use white fishmeal which the fish can digest better. Omega One flakes are great too -- made from fresh salmon.
    I make my own fishfood from beef heart and salmon. The beef heart mix uses 2 #'s of beef heart, cleaned very very very well, a cup of frozen peas, a cup of frozen carrots, a tbsp of wheat germ, 6 oz. of cheap flake food and knox gelatin. You take the BH and after cleaning away everything but red meat, you put it in a blender with just enough water to turn the BH into a thick thick thick paste. Put it in a big mixing bowl. Then do the same with the peas and carrots. Stir all 3 in the mixing bowl. (Key word is THICK not runny!!&#33[img]http://www.**********.com/iB_html/non-cgi/emoticons/wink.gif[/img] Add the wheat germ and stir. Add the flake food and stir it all up. Melt the 4 small packages of Knox gelatin that come in the box in a cup and a half of boiling water and pour that in the mix. Stir it all up and then spoon a cup or so into individual quart freezer bags. Flatten them out and freeze. You should get about ten or so. (Do the same thing for the salmon mix only instead of beef heart use 2#'s of fresh salmon fillets and a pound of frozen cooked and peeled cocktail or popcorn shrimp.) These are good foods, pretty cheap to make -- especially the beef heart -- and really make the fish grow. The salmon is sometimes not taken at first but they learn. Everything loves the beef heart.
    For the Pacus try alot of veggies. They love zucchini slices, big romain lettuce leaves, grapes, bugs, green peas, earthworms live and whole, etc... Put the zuchini in water in the microwave for a couple of minutes until it sinks. That softens it nicely. For a cheap dry food you might check out trout chows on line or at a feed store. They are a great dry food and come in many different sized pellets and in 50# bags. These things could all cut your food costs alot.
    Otherwise on the convicts, feed them well, keep them at 78 -80F, give them alot of gravel to dig in, a large flowerpot, water changes and time and I bet you will soon have 100's. They are usually perfect parents and fascinating to watch they are so attentive. They don't usually hide their eggs too much and the female will tend them. The male stands guard and then helps with the herding. They are very aggressive when with fry and the other poor fish may need rescuing [img]http://www.**********.com/iB_html/non-cgi/emoticons/biggrin.gif[/img] .
    Any questions?

    Bobby

    My first question, can I use chicken heart too? [img]http://www.**********.com/iB_html/non-cgi/emoticons/tounge.gif[/img] we're gonna cook a chicken on Sunday, a extra big one, last time we did that it included the gizzard... [img]http://www.**********.com/iB_html/non-cgi/emoticons/tounge.gif[/img] [img]http://www.**********.com/iB_html/non-cgi/emoticons/wow.gif[/img]
    I am sure the convicts are old enough to breed, when i bought them they were standing guard over a batch of eggs. When i brought them home, they didn't do anything for a while, and after a month they dug a nest, and were just about to spawn, when all of a sudden, overnight, they got ICH! I hate ich, it took me 3 weeks to exterminate all of it...
    Have you read my full journal? you can find the link at the home page of my website, http://www.geocities.com/spectabilis73 [img]http://www.**********.com/iB_html/non-cgi/emoticons/biggrin.gif[/img]
    I've tried the zuchinii, grapes, and F/T Peas, they didn't eat any of them! All they'll eat is Hikary cichlid pellets large size...
    Spectabilis73 shakes head

    I do a 25% water change about 30 minutes before a rainstorm hits the area, I read somewhere that it can induce breeding...

    Hi Spec,

    HMMMMM. chicken heart. I've never tried it [img]http://www.**********.com/iB_html/non-cgi/emoticons/tounge.gif[/img] but seriously, I know people use it or turkey heart. That must be a big chicken [img]http://www.**********.com/iB_html/non-cgi/emoticons/tounge.gif[/img] . I think I would just cut the heart up into little bits and feed the straight heart rather than try the whole mix. If nothing else I bet the Pacus love it.
    It's odd that the convicts haven't spawned again. They must just be freaked out after the move and ich treatment. (Try the product "Ich Cure" next time, it works alot faster but does turn the clear sealer a faint blue **.)
    It sounds like you are doing everything right. Are they alone? Is the temperature right and steady?
    I read 2 pages of your journal -- is there more now?
    Yeah, hikari pellets are expensive. The trout chow would come in a similar size pellet but see if you could get a small sample to try. It's too bad they don't like grapes as it is cool to watch them spin one in their mouth trying to peel it [img]http://www.**********.com/iB_html/non-cgi/emoticons/tounge.gif[/img] . If you let them go hungry a few days you might break their habit of only liking hikari and maybe could get them on something cheaper.

    I used Rid Ich+ to get rid of the ich...
    Yeah, they're alone, and the temperature is a constant 80F. I used to feed them Hikari algea ships, it was 2 times more expensive than the cichlid pellets, and they had to go hungry for a full week before they'd change [img]http://www.**********.com/iB_html/non-cgi/emoticons/tounge.gif[/img] [img]http://www.**********.com/iB_html/non-cgi/emoticons/wink.gif[/img] [img]http://www.**********.com/iB_html/non-cgi/emoticons/wow.gif[/img]
    There's only the 2 pages of the convict journal. after they stopped courting and broke up I thought it would just be a waste of my webspice space to keep going [img]http://www.**********.com/iB_html/non-cgi/emoticons/tounge.gif[/img] ...

    Wow, i'm gone for a day and the convicts take over the place! [img]http://www.**********.com/iB_html/non-cgi/emoticons/tounge.gif[/img]

    No, i don't check the CO2 levels. I'm sorta cheap, and all these tester things are expensive. All i have is a combination kit that tests GH, KH, pH, and useless things like nitrite and ammonia. Also, my CO2 "injection" system is just a 2 litre bottle with yeast and sugar. [img]http://www.**********.com/iB_html/non-cgi/emoticons/rolleyes.gif[/img] I can't get it to last for more than about a week, for some reason, so a CO2 tester is pretty low priority on my list of hobby expenses

    I finally tested the tank parameters again for the first time in a couple months (been distracted by school and CPs), and the pH is right at 7.0, which is a bit strange, but not at all a bad thing, considering my relative neglect. The GH has dropped to 5, but so has the tap water (or my reagents are getting old), and the KH is about where i wanted it with the baking soda additions: 4dKH. Tap water is 2 [img]http://www.**********.com/iB_html/non-cgi/emoticons/wow.gif[/img] Too low for most fish, too high for most CPs. [img]http://www.**********.com/iB_html/non-cgi/emoticons/mad.gif[/img]

    Did a big water change yesterday and dropped the heater thermostat to 72. Unfortunately, it won't cool below 77 right now due to ambient, apparently. No sign of any change from the kribs yet. I fed them krill a couple times this week to fatten them up a little. [img]http://www.**********.com/iB_html/non-cgi/emoticons/biggrin.gif[/img]

    That's an interesting way you have of landscaping your tank. My aquatic plants are too rapid-growing and ephemeral to try to keep them in pots - at least some are. If i started over again, i might keep the amazon sword and the grass in pots. Unfortunately, i started with a normal tank setup with no plans for plants (UGF and big chunky gravel), and still use the UGF and chunky gravel, which isn't necessarily good for plants.

    Yeah, puffers can be pretty psychotic killer attack fish, can't they? I lost a couple of zebras and otos to them (and even more danio fins, which grew back, and oto eyes, which didn't [img]http://www.**********.com/iB_html/non-cgi/emoticons/sad.gif[/img] ) before i put in the kribs. Now, they have turned into such docile kittens since the kribs took over top dog positiong that i'm afraid they'll starve to death because the kribs guard their krill. They're also not very good at avoiding the krib territory, and not used to running, so it sometimes takes several nips from the male to get the idea. Puffers were my first priority when i set up the tank because we had one when i was young, and i'm learning the hard way that they aren't compatible with a lot of things. 6 Colomesus asellus can be quite a handful, but they're really fun to watch. As much personality as kribs, just a bit more psychotic in nature. [img]http://www.**********.com/iB_html/non-cgi/emoticons/alien.gif[/img] Probably doesn't help that they were wild collected and still haven't figured out the glass thing. Anyway, i'm not sure they'd get the krib fry the way they're afraid of the parents, but i guess i'll find out. I can always isolate the kribs if i have to.

    There are two 55W CF bulbs over the tank with a nice reflector (it's an AHSupply retrofit kit). It's a 55 gallon.

    The red algae is just showing up as a hazing or fogging of the glass. It was previously mostly green spot, but now it's got a red hue.

    Cheers
    NL

    PS Spec, i went through Ich about three months ago, too. What a pain. I used the same stuff you did. As far as in know, it's got the same active ingredients as what he suggested.
