i have a community tank with several guppies (3 males, 6 females); 6 killifish, 6 zebra danios, 4 gouramis (2 dwarf), 5 corydoras and 5 bristlenose.
a few weeks ago one of the male guppies was brutally attacked, his entire flowing tail fin was reduced to a stump and he was hiding at the bottom of our metre long tank. i'm not sure who is to blame for this...
i took him out to a smaller tank (no other fish) thinking he'd have to be put down... a day or so later he seemed to be learning to swim with his stump.
its now a few weeks later and he's looking a lot healthier and it seems as if his flowing tail fin is growing, is this possible?! or is it just he's feeling better and has learnt to live without it?
thanks.
