I recently purchased what I thought was a trio of captive bred Talbot's damselfish for my 65g tank from the Diver's Den (Live Aquaria). It turns out they are a totally different type of damselfish called Pomacentrus amboinensis. They are similar colors, but grow slightly bigger from what I researched. There is very little information about keeping this in the reef tank online. I only found information about their behavior in the wild. From what I read, males travel with a small group of mated females, and they burrow a nest under rock in the sandbed to settle in. They have been doing this all day in my tank, exploring the rockwork. I'm worried about how potentially aggressive they are. I intended to get the Talbot's because they have a good reputation but I have no idea about these guys. The larger male seems to be the aggressive one of the trio. The females are not. I saw the male try to nip my algae blenny twice when he crossed his path but the blenny is faster. Now my blenny backs off whenever he comes by. If I see any nipped fins, then I'm definitely removing them.
