I have some brichardi, if they act like a brichardi and form a pair bond they will quickly take over your whole tank and either kill your other fish or have them cowering in a corner. LOL. mine did, they took over my six foot 135 gallon tank, those two tiny fish would beat the crap out of my 6-7 inch venustus male, had him angry and huddled in the corner with the other 12 fish in the tank with them. They are very easy to breed, set a male and female alone in a medium size tank with some rounded gravel and some mini rock caves and you will have more brichardi than you know what to do with, i had to seperate them cause they would not stop breeding. They are not like most other africans in that they dont mouthbrood, they lay the eggs on the gravel and rocks then they hatch in batches, each earlier group as it grows helps to care for the smaller ones. The bigger fry will not eat the smaller fry. I never saw anything like it. coolest thing ever. I do have to say again though, they are the meanest fish i ever kept, i have kept many cichlids and even some hybrid flowerhorns and pound for pound, they are the top of my list for aggrssiveness, i noticed when they are alone in a tank of other species its not nearly as bad, put in more than one and they will take over the tank. Your brichardi look more yellow than mine, i could not decide if i thought they were daffodil or brichardi, they might be a hybrid as others have said.
