I have three large Green Terrors, one large sailfin pleco and a dozen syno. petricolas in a 110 gallon tank.
They have been relatively healthy in this tank for more than a year.
Recently one Green terror started swimming erratically and resting on the bottom. I took it out and had it in a cooler with a small filter.
It seemed to improve so I put it back in the Tank. It now struggles to swim, mostly rests on the bottom when it's not chasing the other terrors away. and can't seem to eat properly either.
It's appearance is healthy other than the redness I noticed at the base of it's fins and the way it just rests at the bottom.
Now the second largest Green terror in the tank is in worse shape.
He seems to be swollen, is swimming erratically and resting on the bottom, has body sores (from swimming into rocks?)and deteriorated fins, his scales seem to be peeling and reddish underneath in spots mostly at the base if his tail fins.
He has no interest in eating and doesn't even notice when I put food in.
I haven't had any other problems other than ick (and PH problems which I still haven"t figured out) so I don't even know where to start. Unfortunately I don't have a Quarantine tank available at the moment and will have to treat the entire tank.
The picture attached is of the smaller terror with the sores.
