Yeah, I wouldn't put them all in, I should have been more clear.

I'm looking for an idea of how many/what would get along with the angel.
The books I've read say a Flame Angel should be OK in a 30 gallon. The mandarin is a maybe, in the future, depending on how everything goes and whether I can find one who takes frozen. I'm not holding my breath!

I know the neon gobies are very small, I had one in a 10 gallon for months with an ocellaris and a shrimp goby.
I had 3 happy fish in the 10, I'm quarantining a Pajama Cardinal to add to the 20, which will make for 4 very small fish.
The angel is a bit bigger, so what can I add to a 29? Peaceful, colorful, friendly...?
