I've gad some silk plants in with my bettas for a while, and I cleaned their tanks today, and one of them is looking pretty grotty. I scrubbed it out as best as I could, but it still looks quite gross. The fake plant isn't too old and I don't really don't want to throw it out, but without any algae feeders in the tanks with them, I'm afraid I will have to regularly throw it out. Any ideas? P.s I'm also trying to figure out what algae eaters I can put in with my bettas to keep algae down... I've had a bad experience with golden Inca snails. I've heard shrimp can work? Can anyone confirm/deny?
