When I said personality, I meant like a Midas or what you might get out of a full grown male dovii. They have great personalities like my male and female "greet" me at the glass Everytom I walk downstairs. However to answer your question about their behavior with bigger cichlids, I have learned that they won't back down. They may respect another fish being the most dominant, but they won't let it beat it up for damn sure. They will fight to the grave, I've especially seen that in my female, she never gives up lol. My male can be a pretty aggressive guy himself, I'll post a vid.
