Do guppys nip fins

Yes, guppies can nip fins, especially when kept in crowded or stressful environments. This behavior is often a result of aggression or competition for territory and resources. Providing ample space, hiding spots, and a balanced male-to-female ratio can help reduce fin-nipping behavior among guppies. However, not all guppies will exhibit this behavior; it can vary based on individual temperament and tank conditions.
