The Golden Endler’s Livebearer (Poecilia wingei) is an extremely colorful, peaceful fish whose small size makes it absolutely perfect for the nano or planted aquarium.  This fish is very similar to the larger common guppy (Poecilia reticulata).  It is very hardy, especially for such a small fish.

Endlers typically occupy the top level of the water column, although they can often be seen swimming and feeding in the middle and bottom levels as well.  They are also not afraid to jump, so they must be kept in an aquarium with either a lid/hood/canopy or at least a significantly lowered water level.  They will not eat or bother plants.   They are safe with other peaceful fish as long as the other fish are not known to nip at the long tail of the endler.  Adult dwarf shrimp are generally safe as well, but endlers may eat shrimp fry.  Larger, peaceful invertebrates can also make good tankmates.  Endlers are best kept in groups or pairs.
