I have just lost 2 of my 4 Firemouth Cichlids. I have around 20 other types of fish in the tank and i test the water once a week which the readings show as ok although my PH has increased from a 5 to 6.5 over 3 months ( which i have been aiming for). The tank i am running is a Juwel Vision 260l with a Fluval 306 Filter, i also have an air sponge filter running. One of the Firemouths started breathing heavily and stopped feeding it was also hiding out of the way near to the substrate but the other 3 where fine. The next day another of the Firemouths experienced the same symptoms. For 3 days they didnt eat but carried on breathing heavily. I added another air stone as i have read that a lot of poeple had experienced this through lack of oxygen and purchased a Herbal additive from microbe called artemiss but in the end it was too much for them.
I was just interested to hear if anybody else has experienced similar problems with these fish as i was really looking forward to keeping just Firemouths but this has given me doubts.
