I recently got back into the hobby. After setting up my tank with a few starter fish, I decided I wanted to try to do a mostly Lake Tang tank. I have 2 Yellow Leleupis, a Orange comp and a Julechromis Marlieri. I also added what I believe is a Vittatus. My Jule went after him quite often.So I decided to get a Julechromis Transcriptus to maybe change his or hers focus. So my big Jule ended up going after the Transcriptus also. Three weeks later they are friends. He leaves the much smaller Transcriptus alone. Today I noticed them both hiding in a cave together. Also the Marlieri is now being more aggresive than usual to the other fish. Is it possible for them to mate? Forgive my ignorance, I am new to these type of fish.
