Diadema Pseudochromis (Yellow and purple)

[mrmaroon]

Can I keep a diadema in a55g with two maroons and a yellow tailed blue damsel? If so, any special care for the pseudo?
If not, how about an Arabian?

Pseudos are pretty fast and tough. I think he would do alright with those. Most other small fish would be in trouble though. I believe they will jump sometimes, so I hope you have a tank cover. Good luck with them.
