1200 gph (Pan World 100pxx) One question I would have for you is how long are your arms? I believe this tank is 29" tall and reaching into this size tank will be tough and lighting is another. But they do look impressive because of the size. If thats what you want go for it. On the angels, for small I like my Flame, on the large catagory go with Juveniles. Blue Face is a great Juvi to start with and Imp.s are nice also. Only one small and one large will normally work in a tank with out a lot of trouble. Just remember angels do not like new tank syndrome, so you will need to wait at least six months for your tank to go through the algae bloom and the water to age. Also I would add low light cheap corals from frags to your FOWLR, they will help with controlling algae.
