Red Eye Tetra

Red eye tetras are easy-going and active. However, you’ll only see this thriving behavior if you have a group of at least six. These fish thrive in a group setting, and having too few fish may lead to shyness and anxiety.

In groups of six or more, the tetras will swim together and create a dance of shimmering light and color. They’re not strictly schooling fish, so don’t be surprised if you see them separate and do their own thing.

Usually, red eye tetras stick to the middle of the water column and swim among plants or hiding places. If you have slow-moving fish or species with flowing fins, you may notice slight aggression. Red eye tetras can nip fins, so you’ll want to keep an eye on vulnerable fish.
