Has anyone tried getting carpet plants to grow over coconut shells? I'm thinking of getting some coconut halves to make caves for my Apistos. I don't think I'd be too crazy about seeing coconuts in my tank, but I thought maybe my DHG or HM could root into the fibers and hide them fairly well.
My other option is cichlid stones, but I think grass covered coconuts would blend in better. I don't think I could ever stand seeing flowerpots in my tank.
