Can an angelfish get hurt if you put a green spotted puffer fish with it?

Yes, an angelfish can get hurt if kept with a green spotted puffer fish. Puffers are known to be territorial and can exhibit aggressive behavior, especially if they feel threatened or are in a confined space. Additionally, the puffer's beak-like teeth can cause injury to the angelfish, leading to stress or physical harm. It's generally best to avoid housing these two species together to ensure the safety and well-being of both fish.
