The Best Aquarium Size for Tetras:

The recommended minimum tank size for the Red Eye Tetras is 35L. These fish are most comfortable when living in big groups, so bigger tanks are always a plus.

You’ll likely need much larger tanks if you’re planning on introducing some tank mates and maybe even more Tetras—usually, the bigger, the better. These fish are active swimmers, so you need to provide plenty of space to prevent overcrowding.

Tank Mate Compatibility:

Redeye tetras are very peaceful; they are best kept in schools of six or more and will claim the mid-portion of the aquarium. Although they are easygoing, they may occasionally nip at the fins of slow-moving, long-finned fish. Redeye tetras are very active in the middle section of the tank and may disturb less active top-dwelling fish. Of course, always avoid larger or more aggressive fish.

Light :
