Small Critter Keeper

These tanks are good for small, single fish or a small school of Zebra Danios, Tetras, Platies or Mollies, maybe even Guppies. I put an airstone in mine to create surface agitation. That, with the wide tank profile, allows for a good amount of surface gas exchanges. A small layer of gravel, a very small plant and an incandescant light which replaces flip up feeding cap make these very nice, compact tanks for small fish.
