[Wet Thumb Forum]-5 gallon Diana Walstad Tank help

[hubbahubbahehe]

Hi Diana and friends,

I currently have a 5 gallon Diana walstad tank, Diana you would love it, it's filled with crypts, vals, marimo balls, baby tears, and pennywort and everything is growing very nicely. I'm having a heck of a time providing circulation to it and i'm wondering if in such a small tank as that it would be okay to run it filterless and without circulation? I currently am housing endler's fry . Any advice or recommendations would be greatly appreciated.
