Can you put a peacock Eel in 10 gallon fish tank and let it live with food?

No, a peacock eel cannot live in a 10-gallon fish tank, and it cannot survive only on food. Here's why:

1. Tank Size: Peacock eels require a spacious environment to thrive. They are active swimmers and need plenty of room to move around comfortably. A 10-gallon fish tank is too small to accommodate a peacock eel's needs and can cause health problems due to overcrowding.

2. Compatibility with Food: Peacock eels are natural predators known for their voracious appetites. They primarily feed on small fish, shrimp, and aquatic invertebrates in their natural habitat. Providing only food is insufficient for their nutritional needs. Peacock eels require a balanced diet that includes live prey to stimulate their hunting instincts and provide them with the essential nutrients they need for proper growth and development.

3. Aggressive Behavior: Peacock eels are aggressive by nature and can be territorial toward other fish in the tank. They are likely to attack and consume smaller fish, making it challenging to keep community fish with them. To prevent aggression and ensure the safety of other tank inhabitants, peacock eels should be kept alone or in appropriately sized tanks with compatible species.

Therefore, it is not suitable or humane to keep a peacock eel in a 10-gallon fish tank or rely solely on food to sustain it. Providing proper tank size, a diverse diet, and compatible tank mates are crucial for the well-being and longevity of peacock eels.
