Stocking for my reef tank

[roisin]

I have a 250 litre (around 50 gallon) marine tank that will be reef when I get around to adding the corals and such. Its been running for about 8 months and the current stocking is 1 coral beauty, 1 maroon clown, a bangaii cardinal and a mandarin. I was wondering if anyone has any suggestions as to what else I could add (if anything). I really like the valentini, leopard and jewel puffers but I don't know if they'd nip at corals. Any suggestions would be appreciated!!
Thanks

Way to early for the manderian

They can nip at coral and inverts. You could go with a wrasse, blenny, hawk, or goby.

The mandarin is doing great, I've had him about 2 months and he's fat and eating frozen foods as well as pods (I have a refugium and add live pods sometimes).
And I was thinking about a wrasse, Ive had a 6 line before but he was a bully and killed one of my clowns, are there any particular species you suggest?

Coris, fairy or flasher would also work. Skip the 6 line, your spot on

Coris would be a bit large for that tank, no?
