Can a keep couple of neon tetras in 1.5 gallon tank or would that be too small an area?

Keeping neon tetras in a 1.5-gallon tank is generally not recommended, as it is considered too small for their well-being. Neon tetras are active schooling fish that prefer to live in groups, and they need enough space to swim and explore.

Here are a few reasons why a 1.5-gallon tank may be too small for neon tetras:

- Water quality: A small tank like 1.5 gallons can quickly accumulate waste and become polluted, leading to health issues for the fish.

- Lack of swimming space: Neon tetras are known for their lively swimming behavior, and a 1.5-gallon tank does not provide enough space for them to move freely and exercise.

- Schooling behavior: Neon tetras thrive when kept in groups of at least 6-10 individuals, and a 1.5-gallon tank is too small to comfortably accommodate a group of this size.

It's important to consider the welfare and long-term health of the fish when choosing an appropriate tank size. As a general guideline, neon tetras should be kept in a tank that is at least 10 gallons in size, and larger is even better. This provides them with adequate space, better water quality, and a more suitable environment for their natural behaviors.
