hello everyone the last couple of weeks have been a pain so im going to vent a little and maybe i can get some advice
it all start when i woke up to a fish with its pectoral fins almost ripped off no real damage other then the fin but sadly it died over night
then over the next day or so i noticed one of the remaining fish getting singled out by the other 2 it got to the point where i divided the fish but then it stops eating (for a little more than a week ) yesterdays i noticed it had a cut on its head i didn't think much of it but again it died over night
tank stats 110 us gallons 60 18 24 L W H there was 4 severum in it now 2 i have 3 canister filters running a weekly 75% water change i don't have a ammonia or a nitrite test kit right now but my nitrate 10 ro 20 ish PH 6 to 6.5 GH 3 or 4 drops KH 1 drop
at this point i don't know what to think i will post some pictures maybe someone can see something any help would be appreciated
