Bulgarian seal point angelfish
Bulgarian Seal Point Angelfish .... Pterophyllum scalare.
Angelfish are about as Bulgarian as Rams are Gernam, but apparently it was a Bulgarian who first produced these (I researched that. Did wonder where the name came from).
Anyway... Angelfish. Some people love them, some think they are devil-spawn. Usually, people in the latter camp have either had them in too-small tanks or with small fish, AKA angelfish food.
Yes, they eat things like neon tetras. Of course they do. A lot of people dont realise that angels are cichlids, and are therefore predatory and territorial. Fantastic fish if kept in the correct environment. Terrors if not.
Give them plenty of space and company... These are a shoaling fish outside of ther breeding season, but can live as pairs if you can't house a lot of adults together. If you want to keep a few, plant the tank and use decor to break up sight lines. That way, if a pair decides to spawn, the others can get out of the way without being relentlessly picked on.
