Earlier today, at about 8 o'clock I was taking some pictures of my VT, Uva. He has such nice fins. He seemed to dislike the camera though, he was flaring every time I approached his tank. Later today, about 3 hours later I come back to my room to see his fin is completely devoured, I even saw him doing it!
He's in a filtered 5 gallon, heated at 80 degrees, lots of space to swim and hide. He seems just as happy and active as before, just now with ragged, bitten up fins.
I know I have to monitor him now to make sure he doesn't get an infection :( My 50% weekly changes have kept water quality stable. Why do they do this ?
