compatibility Q's?

[reef_doug]

Tank is 180g. Inhabitants are Chromis, YT, Purple Tang, Hippo Tang, Flame Angel, Coral Beaut Angel, Stairry Blenny, Diamond watchman goby.

1. Can I keep a (Fridmani)Purple pseudochromis and a Purple Firefish?

2. Can I keep more than one psuedochromis?

3. Can I keep more than one algae blenny (such as a Stairry Blennie and tailspot or lawnmower)?

4. Will a Leopard wrasse be compatible w/ Blennies and psuedochromis?

Thanks
Doug
