[Delphinus]

Ok, I was going to stop talking but Brett's making me keep going. I'm completely innocent here.

FWIW, J&L also has orchid dottybacks in right now. They fit the bill for a splash of colour (not red or yellow but damn they are a sexy colour), open water swimmers (although like to have caves in rocks for a place to hang their hat), and generally regarded as the least aggressive dottyback. I'm not terribly certain how he would do with your other tankmates. Possibly OK, but ... I don't know for certain.

Mine is in a 115 cube and although the smallest fish, doesn't really fear anyone (but I see no issues of aggression). He did get a little cheesed when I added my eel, I guess as a fellow save dweller he didn't appreciate having to share all the rock holes. So he would swim very angrily around the eel when the eel was out. "Swim! Dart! Swim! Dart! Look at me! I'm small but I'm fast. Swim some more! Dart some more! Hey, come back here! I'm not done swimming towards you. Yeah I'm swimming to YOU buddy!" That's all it ever amounted to, the eel is mostly blind and took no notice, and they seem to accept each other now anyhow.
