Looks good..love the volcano!! I have a couple of angels also and they get quite large, may want to keep that in mind even in a 55 gallon ;p ...the biggest one is a bit aggressive toward the smaller one...nipping at it and keeping it "in its place" so to speak..not sure if i have a pair or not (sounds like it) but..the bigger one is at least 5 inches tall and very thick..he looks like your black and white marbled...so..KUDOS!
