The hoplos are 4 inches!! Well, the adults.The pleco seems to fit right in, all out & about. I had to wait & maybe squint to see the garras' little white tummies. They seem so small but not bite sized. & I thought your hoplos were little, lol.
I have; but it mostly just grow on the snails.... so it isn't a problem with the plants. I reduced photo period to 6 hours a few months ago; i suppose i could go to 5 but worried it might hurt the flamingo crypt.Great thought, Dee, I love it! I guess I had ramshorn or pond snails to keep my mystery snails cleaned up the couple times I had them. I never had that alga problem.
Jake, have you tried picking off most of algae clump & shortening your lighting photoperiod? That's where I'd start...
