Since yesterday oene of my silver tigers is in a right state. Yesterday it was leaning and could not use its right side fin and today it cant use either side it just lies flat on the sand unless something comes up to it then it can swim straight just using its tail fin. What could be the propblem it just hits the gravel and lays there, now I know the fish wont make it but do any of you guys no what the problem vould be could it of been stung by one of the rays? Or chased by the aro and hit the glass and broken its back? Also the fish is still alive should I just put it out of its pain??? Water prams are spot on? Stocking it: 1x12" green asian aro, 1x10" p.bass but the aro wont let him come out, 4x silver tigs, 2xrays, 1xfire eel, 2x birchirs these are only about 4-5" long, 1xroyal plec, 1xsorubim lima and an ornate pim. Here are some pics of the poor little guy.
