I have 5 orante bichir. One of them is in another tank for treatment fir his bloat. They are all pretty small about 8-9cm. I noticed one of them has his tail "torn" instead of having his tail a whole piece, the soft part that connects the bony "strands" are not there. Is this due to rapid growth causing the tail bone to stretch and tear the skin? or is it aggresstion between bichirs? will the skin gorw back to connect the bony portion to make the tail a whole piece again? (sry if my description is not that gd)
