I recently bought an aquarium. I have not had one since I was quite young. I bought a 125 gallon that said it came with 20+ fish. I got there and the tank was a mess and there were 14 African cichlids a cuckoo catfish and a pleco. All of the cichlids looked sick. I cleaned the tank up and bought a new fx6 filter, two new heaters, a power head and I have two aquaclear 110 filters on the way as back up. The cichlids all seem to be doing well now other than the one that died. They all had sunken bellies. I bought Cichlid pellets and some spirulina flakes and some blood worms and mysis shrimp. Is there anything else I should be feeding the catfish and pleco? I don’t put the blood worms or mysis shrimp in very often.
