Yep, I'm with Reiv.....add some rocks or driftwood in there and it'll give more interest to the scape. I'd also slap on a background....I like plain black for my tanks, though I have seen landscaped backgrounds that work very well too.
Your angels have a bit of growing to do before they show any spawning behavior. Mine are about 2 inches nose to base of tail...and have only JUST started to exhibit some interest in that area. Nice lot you have there.
The plants look nice and healthy Phantom ! Great job !
