Rummynose tetras are naturally found in the blackwaters, close to the Atlantic coastline of the Amazon river in South America.
The water is soft but acidic due to humic acid decay from leaf litter on the soft sandy substrates of the riverbed.
Rocks and caves are common, along with plenty of planted areas providing shade and foods.
Use pellets or flakes as the staple of their diet, containing all the nutrients they will need and maybe give them additional treats once or twice a week.
Both frozen and live foods are great ways to provide them with some protein, bloodworm and daphnia are good choices. Any leftover green vegetables can also be added into the aquarium providing you chop them into small pieces.
