Convict cichlid breeding

  • We are currently upgrading MFK. thanks! -neo
In a 20 gallon, 2 males will probably not co-exist forever. If they are small, you may have a while. Switch for a female would be better, or even better, keep your favorite male and try some quick dither fish like swordtails.
The last guy's advice was not good in my opinion. We know the sizes convict cichlids can grow to as a species, and their average temperament. This will be true of convict cichlids in my tank, your tank, his tank. You don't always have to "learn only from your own experience" when there is a wealth of information available today from people who actually know what they are talking about. Will save you from experimenting too much unnecessarily. I'm sure the fish will appreciate not having to be guinea pigs.
That said, convicts in a 20 is not the worst situation. I've bred them in smaller before. But to me, a 20 will eventually be too small for a pair, but should last you until the male is about 4" TL. To grow beyond that and reach full potential he may need a larger tank.
 
My convicts are doing awesome and I realized that I have 2 males
You might have to separate them ,i had 2 males in a 33 gallon they were only about 2" and they were fine and didn't mess with each other.Then one day i walked on a full on prison riot in my convict tank the bigger white convict was beating up my albino bristle nose and the slightly smaller black convict eventhough i separated them and medicated him my black convict died 2 days later.
 
I don't think I want to breed them now after I have had my guppies breed and have 100+ fry. I might try to rehome the second male. The male that I really like right now has gotten to about 3 inches long and really colorful. I didn't want to have them fight so I moved the second one into a ten gallon about 1 month ago because they were getting territorial and starting to fight. Thanks for the advice Gourami Swami Gourami Swami
 
Would it work to put up a divider in the 20 gallon? I am going to the fish store later and I might be able to get one.
