It comes as a surprise that red eye tetras are super easy-going and friendly. Their pleasant traits can adapt well to any home aquarium.
This tetra type is one of the most good-tempered aquatic fish. Thanks to this advantage, they are usually adopted in groups or kept with other species. The fish is active in the middle of the tank and often swims through dark or shaded areas.
However, some experienced people have shared that they can mistakenly bite the tail of long-tailed and slow-swimming fish. Apart from this caution, red eye tetra is regarded as an amiable resident in the tank.
How Many Red Eye Tetras Should Be Kept Together?
If you are bound to adopt only a school of tetras, you are possibly more generous with the number of members. These tetras prefer a swarm environment, so feel free to add more tetras. However, a school of 8-10 is considered ideal for a standard indoor tank.
With smaller tanks, you should still maintain a minimum of 5 for a school of tetras. Too few fish in a group can lead to common mental symptoms in fish, such as loneliness and stress.

Besides the same species, tetras can still coexist in harmony in a diverse environment. Yet, choosing tankmates needs more attention. As we shared, you should not keep them with long-tailed thin-fin fish (e.g. betta fish) or large, aggressive fish to avoid conflict in the mini marine.
Instead, it would help if you considered species that share the resemblance: pleasant mind, small body size, short tail-fin, and active movement. Tetras can also make good friends with dwellers at the bottom of the tank. Rainbow fish, guppies, barbs, danios, or neon fish can become the optimal choices.
