> Can I keep them in a planted > 38 with PH 7.6 and med hard water? They don't need the plants, but will leave them alone, digging around them to excavate breeding space. They form a breeding colony, only one adult male in a tank your size. Young from consecutive broods help protect the younger babies. > Are they very aggressive? Mine tolerate a discreet, but full grown Julidochromis. He stays in the corner in a pot of his very own. Two breeding females have nests at opposite ends of a 20 high. That is smaller than ideal, but they have been in there for four years. South Americans would be terrorized. I keep young brichardi in a grow out tank and they intimidate Laetecara thayeri and Apistogramma males that are larger in size. > Are they very difficult to keep? Not at all, once the extra males have been killed off, or rescued by a kindly owner Thanks in advance, Teresa.
