I have nas, turbo, ninja star, asternia, orange, nerite, and stomatella (snails) blue leg, scarlet hermits a sally light foot, arrow, and 3 emerald crabs and I have a skunk cleaner, fire, and a peppermint shrimp all in my 65. The sally lightfoot eats more than anything in the tank, he alone is a great CUC. But I still have cyano growing on my SB and some of the rock. I have been repeatedly switching out my phosguard and vacuuming my cc as well and still it grows, NOTHING eats of cleans it up just keep fighting!
