I have 4 pictus in a 46 gallon bowfront. We. Had 4 molly's with them but the pictus stressed them out and were nipping the tailfins so we rehomed the molly's. The issue is algae now. We are getting brown and bright green spots on the rocks and decor so are wondering if anything could stand up to the hyperactivity of the pictus and help keep the algae at bay. I don't have driftwood and don't really want to add any. Unless I could get by with just a little piece in the back.
