Whether an attack or bite occurs between a kissing fish and a guppy depends on a number of factors, such as the personality of the individual, the size and layout of the fish tank, and the availability of resources (such as food and territory). Here are some considerations:
1. Fish personality: Each fish has a different personality, some may be more aggressive, while others are relatively mild. Kissing fish are usually more peaceful fish, while guppies can also be relatively friendly species. However, individual fish may have aggressive or territorial protection behavior.
2. Size and layout of fish tank: Providing enough space and proper layout can reduce competition and conflict among fish. If the tanks are too small or poorly laid out, fish may compete for limited resources and increase the incidence of attacks or bites.
3. Feeding and environmental management: Good feeding and environmental management are important for promoting peaceful coexistence. Providing adequate food supplies, proper shelter and swimming space can help reduce competition and conflict. In addition, maintaining good water quality conditions, cleaning fish tanks regularly and monitoring the health status of fish are also the key to prevent problems.
