The Rummy Nose Tetra is a popular choice for live plant keepers and Discus fish keepers. The rummy nose is very peaceful and can make excellent community tank mates if housed with similar sized and non-aggressive species.

The do best in schools of 6 or more and may stress if not provided with hiding places and aquarium plants (plastic or real). They have a red colored nose and it can be quite striking to see a school of them swimming around a tank.

The Rummy Nosed Tetra can be sensitive to pH fluctuations so take more time during acclimation and during water changes.

This is one of three species that can be easily mis-identified because they all look very similar. There is the True Rummy Nose (Hemigrammus bleheri), the Rummy Nose Tetra (Hemigrammus rhodostomus) and the False Rummy Nose (Petitella georgiae). The H. rhodostomus and P. georgiae grow to about 3 inches (8 cm) whereas the H. bleheri only reaches about 2 inches (5 cm). The H. bleheri will also have more red coloration on the head and appear thinner than the other species.

For fish food, they are omnivorous so try to give them a varied diet. They will accept flakes, frozen, freeze dried and smaller live foods.
