    An extreme case of such deformities has been brought to my attention recently which inspired my conclusion to this age old fish myth. I wish I had felt better to go to the store and take a photo of this FW silver tip catfish before it was justifiably put down.

    The fish was well over a foot in length, close to two feet and was raised and kept in a 20 gallon tank. How did the fish keep from out growing the tank? It's spine had grown to give a sharp deep V into the animal's back. It folded as it grew to avoid growing out of it's environment. The owner of this fish gave him to us. When placed in a 125 gallon aquarium, it was evident the animal was incapable of swimming because of this extreme deformity. It was a pathetic sight and sadly, he was put down, though with the fish's best interests in mind. His face pointed to the sky, his belly drooped on the bottom and his tail was as high as his head. A clear 90 degree angle.

    I have heard of people keeping large species of fish in small tanks for years without any noticeable growth when there should be. More likely this "dwarfism" is due to poor water quality and poor nutrition.

    Either way, it is cruel to attempt to keep a large species of fish in a small environment. They either end up sickly or severely deformed.

    NO, this is an absolute myth. Fish do not stunt to fit a smaller tank any more than you would stunt to live in a smaller house.

    by putting a fish in a tank that is to small for it you condemn it to stress, disease, and eventual death. Period.

    An example from the salt water world would be the Tang, it needs a large tank not neccissarily for it's size, but because of it's habbits, it needs to be able to swim to feel normal.

    Putting an aligator gar in a 100 gallon tank would be an exercise in irresponsibility. your talking about a fish with a max weight of 300 lbs.

    Tell me how you think a fish that can grow this big:



    would be comfortable in a 100 gallon tank?

    if you want to keep predators, especially large predators, you need to save your money and start thinking THOUSANDS of gallons, not hundreds. fish this size simply should not be in normal aquariums.

    If you want to keep some cool predatory fish that are suitable for a 100 gallon tank, try these:

    Fresh Water
    Weeksii Bichir - 1ft 8 inch carnivore
    Oscars
    African Knife
    Knife fish
    Freshwater Lion Fish (Batrachomoeus trispinosus)
    (just off the top of my head)
    (note you can't have all of these, predators are messy and you can usually keep only one or two!)

    Brakish Water:

    Brakish Puffers (there are a few)
    Leaf Fish

    Salt Water:
    (suitable for 100 gallon or less)
    Some Parrot Fish
    Some Puffer Fish
    Trigger Fish
    Any of the Dwarf Lions (a single volitans lion if you only want one fish)
    Frog Fish <- talk about aggresive!!!!

    That is just the tip of the iceberg!

    If you gotta go fresh, I reccomend a Bichr, it was my favorite fresh water fish.

    Your gonna need one hell of a filtration system for any of these fish.

    So leaving a channel cat in a 100 gal. Is irrisponsible? In pet stores I've seen aligator gars in 30 to 55 gallon tanks doing quite fine.. I'm not arguing I just want what's best for these guys, truth is, I already got the channel cat fish, they are about 2 inches long, the nearest I can get the 100 gallon is july

    Channel cats get very large so yes that would not be a wise permanent home.

    Just seeing a fish in a petstore doing fine means very little actually. They usually only stay in the tanks for a few weeks till they are moved out to hopefully better homes.

    Fish are also very resilient. Even in poor conditions they can hold up and still manage to survive(though this probably isn't what you want to do in captivity). Examples of this would be when ponds grow too large of fish populations the fish will stunt. Things like Bullheads and Tilapia sometimes end up at around 5 inches or so. Dunno about the bullheads but Tilapia are able to breed at only 2 inches so even in such conditions may still persist. That being said this isn't something you should try as an aquarist.
    1 Nxventrata

    D. muscipula & D. muscipula &#39;Red Dragon&#39;(barely)

    Sarracenia leucophylla(seedling)

    S. purpurea and Drosera filiformis filiformis/ intermedia seeds waiting to sprout.

    If you think a retail store overcrowds their tanks, you should see a wholesaler! It is typical to bring in something like 300 platys and shove them in a 20 gallon tank, on arrival. But they are drugged with anti-bacterial meds and the idea is to bring them and move them out as quickly as possible. A retailer does the same, but they have fewer in a tank and they move more slowly. The mentality is different for those who sell and those who keep. Go with what RamPuppy espoused.

    In ANY tank the largest fish you should have should be LESS than 3/4ths of the tank width (front to back) in it's total, adult, length. The largest fish, then, would be something Oscar sized. That... pushes it. You then have to consider how much bulk of the tank is taken up by decoration, and how much filtration you need... for large carnivores you would need a canister filter at the least.

    For an example of how to house these large, native, fish... I show you the following: http://www.roadsideamerica.com/attra...sspro_tank.jpg

    You're talking dozens of square feet (no, hundereds, if not thousands). You're talking TENS of thousands of gallons, and VERY large tank areas for these fish. Anything less is not only irresponsible, but cruel.

    You don't stick a dog in a cardboard box and expect that it'll be just dandy. You don't stick a kid in a closet and expect them to live the rest of their life there... people that do those things go to jail for cruelty and abuse. It's the same principle.

    Responsible hobbyists do not go "Welllp... I got 'em anyway. Sure, I can't care for them... but I already got 'em, so I'll just do it anyway with the wrong equiptment."

    How about not buying fish you were already warned against purchasing in the first place?

    Somehow that seems the best choice.
