I hate to admit it but it’s been forever since I’ve added any sort of cuc to my tank. I had a few hermits but the big ones ended up evicting the Smaller ones from their shells and then they just sort of all disappeared. I’ve got one lone snail that was a hitchhiker but I need some more snails/crabs. What are your favorites for bare bottom tanks? I’ve got a little bit of hair algae that the hermits worked on And I’ve got some detritus buildup on the bottom.
