Convict: ( Archocentrus Nigrofasciatus)
Quite aggressive for such small little fish.
Size: 3-6 inches
Aquarium Size: 15-75 gallons
























Convicts are know for two things: Being aggressive, and breeding like crazy! They are very common and hardy cichlids. Their names refers to their pitch black stripes that rest upon their light black colored bodies. They are quite small, especially when you see them in the store. But do not be decived; pound for pound, ounce for ounce, the Convict is one of the most aggressive fish. They will fight and harass fish that are even twice their size. They have been known even to bully Oscars and stand up to Red Devils.

If you plan on keeping them with other fish (and letting the fish live, right? I’m assuming that when I write all these articles), then make sure the tank is big. They will destroy your average community fish, for example barbs, gouramis, tetras, as well as fish like Firemouths, perhaps the young of other cichlids, and Convicts themselves.

Now for the second thing Convicts are so well known for. They breed like  rabbits. Ask anyone who knows shit about fish, and they will tell you that Convicts are one of the easiest fish to breed. After a brood is removed, they will get to work on the next. They are great parents, and viciously defend their young. At that point, it would be wise to remove anything from the Convicts’ tank (unless you want it dead).

Breeding: As mentioned earlier, convicts are easy to breed. While it can be done in a tank as small as 10 gallons, one convict may constantly beat on and kill his or her mate (personal experience). For this reason it is better to have a larger tank, such as 29 gallons, or even larger. It’s a good idea to have a clay pot that is half dug into the gravel, for the female will lay her eggs in there. Convicts are great parents, and will protect their fry from anything-this includes YOU. There have been countless human deaths that could have been easily prevented-don’t stick your hand in a tank with a pair of breeding convicts. You have been warned.

Once the fry have used up their yolk after a few days, you can feed them powdered fry food, artemia nauplii, or even just finely crushed fish flakes. They will grow rapidly, so make sure you have a place for the babies to live when they grow up.

Convicts are tough, and can handle a pH anywhere between 6.2 and 7.7. It is recommended to keep the pH near neutral though, perhaps a bit on the acidic side. Convicts will do fine at temperatures of mid to high 70s.

So good luck keeping this little devil!!!!! 🙂
