Who Gives A Fish Forums

Water Wisteria is a good pick. Just be ready to trim it weekly. It'll take over if you let it. I've also had success with Rotala Indica in high flow, but it needs strong light to stay compact.

Yeah, Rotala's a beast if you've got the light. My high flow tank's got CO2 and it's growing like crazy. Just don't skimp on ferts or it'll get leggy.
