Everyone has been very helpful here @ Fishlore and help is much appreciated but i have another problem. I posted a little while back about my long finned rosy barb swimming funny but I decided not to use the same thread as I have finally found the problem. I wanted to be able to get specific advice. His tail fin is split all the way up. I don't have sharp surfaces in my tank and I have never seen a real fight. My Bolivians threaten each other and lip lock now and again but never bother the other fish. I figure the tear got worse when I was trying to figure out what was wrong because his swimming has got progressively worse. I have him in a hospital tank now and am treating for fin damage with maracyn oxy. Will this ever heal or is it too bad now? He is struggling so hard to swim (a lot of the time swims in loops or circles) his breathing is labored. His color is almost nonexistent. He is eating fine but looks horrible. Scrawny and possibly even has shrunk. Is there anything I can do? Thanks in advance.
