I recently lost some U.gibba which had been snuck into a fish tank I maintain with some java moss. I had noticed the bladders and very fine hairs coming out of them and kind of knew what the plant was. It was really more of a novelty to me and the aquarium owners untill my interest in CP's peaked a few months ago.
The fish tank ended up with a nasty hair algae bloom that obliterated the Utric and all I could find of it was a tiny 2 mm stem fragment with no bladders. I carefully picked it out of the filter media with tweezers and took it home to see what would happen. I put it in a small cup with distilled water and despite its pale color it produced a bladder or two before shrinking and dying in a gooey blob.
I am ready to try it again and the fact that it grew and reproduced so well in the fish tank (before the hair algae incident) leads me to believe that it needs a little "dirtier" water than I gave it with the distilled.
Can anyone offer some tips on how to grow this fun little aquatic? Should I add some soil to the water to prep? How about water hardness? It didn't seem to appreciate the water I use for all of my other CP's.
