I am still trying to decide how to finish my tank off. I want to keep any breeders pure. Please help me out. If I get one group of haps and one group of less aggressive mbunas, will the interbreed? I have heard conflicting information about this, such as they will if they are similar in color or they will not as long as each has it's own large group or they will not no matter what. I know this is the best place for information, but for some reason I seem to have trouble getting responses. Any advice at all would be appreciated.
