hi I am new to peacock bass.. just picked up 3 2" bass from a local pet store. they all looked pretty skinny when i first bought them. withing 24 hours the first one died. got a refund. got the other two eating rosy reds and looked to be doing well. all of the sudden one of them stopped eating. they are both in a 29 gallon for now i have a 55 set up for when they grow a lil bigger and then a 150 after that. i have had the tanks for the past ten years. all established.... kepted african cichlids. changed water and made softer with lower ph for the bass. any ideas? i am worried another might die!!! only got them on the 17th.
