If you have any less than a couple hundred gallons, dont even consider this. Ill come back and edit this with a link for red terror info, but you obviously didnt look at the dovii info very much, if at all.
Female doviis get about 22 inches. Males can get 30 inches. Both will eat the firemouth and the convict. Males are extremely territorial and will kill most other fish once it hits around 12-16 inches. Doviis/Wolf cichlids are often called psycho fish, and for good reason.

Regardless, your tank is probably too small for most of these fish. But if you have an adequate size (somewhere around 500-600 gallons) then I envy you.
That doesnt matter if they are all small, they all get big. What size is your main tank? Because a wolf cichlid will outgrow a anything less than a 200 just by himself. And him a fish that has an attitude like that to have tankmates, youll need a few hundred gallons on top of that.
The smallest fish you have in that tank are the convicts and firemouths. Both get around 6 inches. Other than that, you are looking at 10+ inches of fish for each one. The dovii in particular at 22 inches for the females, and 30 inches for the males.
lmao. 350 gallons. You are a beast. But still, that dovii will probably end up claiming most of that tank. But other than that... The convicts and the firemouth are the only ones in trouble of being eaten. And a 55 gallon should be fine for a single convict and a firemouth. But youll still have to worry about the others if the dovii does decide the claim it. If you end up with a female dovii, that will probably be for the better. She will stay smaller and be less aggressive.
