Hi Justin. I have raised cichla a couple of times before, but I have always had to get rid of them around 12” because of cross country moves. I have never lost one (knock on wood). They are pretty hardy fish, especially after they reach 10” or so.
I’m hoping this time around I’ll be staying put for a long time, so I have ordered a 650 gallon (120”x42”x30”). In the meantime, they are growing out in a 100 gallon and currently range from about 5” to 8”. Filtration on the 100 gallon is an internal wet dry, two Fluval 406 canisters, and a Fluval FX5 canister that I’m not happy with and will soon be replaced with an eheim 2262.
Filtration for the 650 will be two large bead filters for pools and 2 eheim 2262 canisters. Hopefully it will be enough; there will eventually be a lot of big fish in there.
