Are they ANGELS in the TANK?
They can be territorial, more so when in pairs. They can eat small fish, such as neon tetras. On the other hand, some fishes, such as tiger barbs, can nip the tail of an angelfish.
When it comes to community tanks, the larger, the better. The more angelfish there are in a community tank, the more they can focus on their own species. Besides, an all-angelfish tank is a sight to behold. They look good with driftwood and plants.
While they say angelfish and goldfish don’t mix, I have had no problems having them together.
