Lemon Tetra

Overall, the lemon tetra is an easy-going fish that likes to keep the peace. They are active and playful as well!

Like many other tetra species, lemons prefer to stay in groups. Without a group, the fish can become reserved and anxious. This will eventually lead to health problems in the future.

Throughout the day, the fish will group up and explore. You may notice some light aggression between males. They can get showy as they try to court females, which results in small battles here and there.
