Can a sucker fish survive with black angelfish?

Answer 1

Yes, a sucker fish, commonly known as a Plecostomus, can generally coexist with black angelfish in a community aquarium. Both species have similar water parameter requirements, and the plecostomus helps keep the tank clean by eating algae. However, it's important to ensure the tank is large enough to provide plenty of space for both species, as angelfish can be territorial. Monitoring their interactions is essential to prevent any stress or aggression.
