The fish does not eat, it's swimming alright even though no fin. I have a wavemaker but i doubt it would got sucked into it. Other fish nipping on it because it was weak? I got rams in the tank, but they are usually not agressive. The tail is a little bit white on the edge, a little ragged, but there is no fin whatsoever, looks like the tissue that holds the fin is still there though. hard to see because i have it in a bucket atm
Bump: The best pictures i could get without taking it out.
