PaigeIs Posted March 2 Share Posted March 2 Hello All, Has anyone tried growing brown diatom algae on rocks outside the tank? I ask because my otos love it. I'd like to grow some algae-covered rocks to use as supplemental food for them. I already give them Repashy and vegetables, but they must compete with the platies for those foods. I think they'd like to have a nice algae-covered stone now and again, but I'm unsure how to do it. Meet John Wick Link to comment Share on other sites More sharing options...
