Can a pleco be in a breeding angelfish tank?

Yes, a pleco can be kept in a breeding angelfish tank, but care should be taken to ensure compatibility. Plecos are generally peaceful and can help with algae control, but they may disturb the breeding pair or fry. It's important to monitor their behavior during the breeding process, as the angelfish may become territorial. Providing plenty of hiding spaces for both species can help reduce stress and aggression.
