One of its more unusual characteristics is a swim bladder divided into two lobes such that it resembles the Greek letter pi. Because this fish is so transparent, this feature is easily seen.
They are a hardy and undemanding fish, they are easily able to being their own individual flair to your planted or aquascaped aquariums and are best kept in groups of 5 or more.

Tankmates, if any, should be similar in size and temperament, and ideally species that occupy different levels of the aquarium. They feed readily on finely ground flake food, but appreciates live and frozen foods too, particularly daphnia, small bloodworms, etc. This stunning fish is best kept at 24-27C with soft, slightly acidic water being preferred.
