My Modesta never tolerated any fish in his cave. He would fiercely defend it form any fish in the tank. He especially hated the dominant female Clown loach(over twice his size) and would leave her marks/gashes on her sides if she tried to invade.
That is until I introduced the baby clowns. He now has totally calmed down and keeps the youngsters safe at night. Sometimes I see them swimming all around him but usually I see them lying sise by side or they sometimes rest on top of him. When he eats, he never challenges them for food like he did with the adult clowns.
