Community planning & swim zone pressure

When planning a community around Serpae Tetra, consider the aquarium swim zone pressure. This species primarily occupies the middle zone. Because Serpae Tetra is territorial and defends that zone as it matures, do not balance the setup with more fish competing for the same space — choose calm tank mates that stay out of the middle zone instead, and check each pairing with the compatibility checker before mixing.
