So my community tank is being looked after by my partner at his house, who likes looking at the fish and talking top them but not much else... he went to feed them tonight and discovered my leopard corydorus swimming erratically, as he put it "doing barrel rolls". He had tested the water before ringing me,
Ammonia 1-2ppm
Nitrite 0
Nitrate 20-30ppm
Temp is 23 Celsius (subtropical tank)
Stock:
1x 3in goldfish
2x 4in weather loach
3x 2in peppered Cory
1x 1in sterbai Cory
1x 1in leopard Cory
2x 1in Borneo loaches
4x 1in zebra danio
4x 1in wcmm
5x zebra nerite snails
Filtration: fluval u4 running purigen as well
When he rang me, I guessed ammonia poisoning was what was causing the erratic swimming, and also the lack of movement from the other fish in the tank.
He refused to change the water without me, so after an 11pm trip to his house, I did a 50% water change and used 7.5ml of prime (tank volume around 100l)
After this the Cory seemed to be able to swim a bit better but was still listing slightly to the left. So my question is, apart from daily 50% water changes until this spike is over and using prime to detoxify the ammonia and nitrite, is there anything else I can do? Would you agree with the diagnosis of acute ammonia poisoning? There was no sign of bloating or parasite and he was fine two days ago...
Any idea on why the tank crashed? They were last fed on Tuesday, and get fed two to three times a week. We have lost no fish that I can tell and there hasn't been a power cut. The tank was left unattended from yesterday afternoon till this evening , no lights and no feeding. I'm really confused about the spike :-/
Anyway, hope this makes sense, I'm getting better at dealing with illness and I just want to make sure as a relative newcomer to the hobby that I'm doing the right things in terms of acute care.
Thanks for reading
