I've found it makes a good hospital tank for ill fish. Its the perfect size so dispensing medications is more cost effective. Plus, you can route in a penn plax smallworld filter (minus carbon, because that takes medication out of the water). Sick fish need aeration, and it works in this small tank. Never, ever make this kritter keeper a home for goldfish. Contrary to popular belief, goldfish need lots of water to make up for the massive amount of waste they produce. This size would be alright for a betta (who should never have less than a gallon of water, again, contrary to popular belief), maybe a trio of guppies if you have a filter. This kritter keeper is great, as long as you know how to properly use it.   1     2   Non User
