As with most members of the Salaria genus these are brackish fish that need salt in their water for their long term health. They are quite difficult to feed, the ones i had would only accept small live foods and they have large appetites and a fast metabolism so need to be fed every day and prefferably twice. I found that once they had grown to around 2 inches they became aggressive to each other and the largest of the 3 i had killed the smaller two, some time shortly after that the fish started to refuse food and eventually died.
