Community planning & swim zone pressure

When planning a community around Paradise Fish, consider the aquarium swim zone pressure. This species primarily occupies the topmiddle zone. Because Paradise Fish 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 top and middle zone instead, and check each pairing with the compatibility checker before mixing.
