So, as a ploy to get my husband I tested in my tank (and there by default assist with maintenance) I have decided to let him pick out our new inhabitant. He has his heart set on a marble veil tailed angel and really only wants that and nothing else. I have heard that angels can be nippy and territorial and I have zero experience with them. I have guppies, a Molly, a BN pleco, Cory cats, and a couple snails. I plan on getting shrimp in the near future? Liveaquaria says angels are compatible with all these? Any thoughts? I have a 55 g by the way.
