I was thinking of putting about 5 of each in my 6gal nano. What i was wondering what kind(s) of anemone are best for these guys to hang out by? Any cool anemones that would look kool with these guys keeping safe by it? Would they be compatible with each other at the same anemone or would i need multiple? Also would harlequin shrimp bother the anemone shrimp or crabs? Also i have brown algea growing on my anemone crabs how do i stop it from growing on them?
