A single nerite snail will assist keep algae under control. Nano Fish Species: Very few fish types are suitable for a tank this size. Endler's livebearers (males only, to avoid overbreeding) or Microdevario kubotai (emerald dwarf rasbora) can work, however only if the aquarist is knowledgeable and maintains extensive water quality.
