5 gallon nano fish?

[miniz2k6]

can i keep a clown goby in a 5 gallon tank? what else can be put in with it? will the HOB filter work? it will have at least 5lb. of live rock and weekly water changes. what kind of clean up crew should i have?

One clown goby would probably be the limit. Maybe a couple of neon gobies would be a better choice.

A hob will work fine for flow depending on the GPH.

I have three hermits and one astrea snail in my 5.5.
