Bought two 3.5” monoculus 3-4 weeks ago..have been doing great eating Vibra bites and small pieces of tilapia. Liked them so much ordered 2 azuls and 1 more mono. Everything seemed to be going alright, scrubbed the walls of the tank and did a water change and the two original bass turned dark stopped eating where breathing hard with mouth open and within 2 days both were dead. The new 3 still are doing good and eating well. Just want to make sure I give the three I have left every chance to make it. Only other tank mate is a baby silver aro. In a 40 breeder with a 407 canister filter good aeration doing 25% daily water changes and 50% every third day ( do daily changes on the discus so figure why not do them also).this set up is just a qt/ grow out to get them big enough my rays don’t try to eat them. Right now running a course of metro/Prazipro and salt @ 1tbs per 10 gal. Temp like 82. Is there something I’m over looking? Could it have been just stress?
