Was concerned my Sally light foot crab would not find enough to eat Low and behold, she likes coralline algae Marc, I noticed you may have posted a frag pic of this few SPS coral I have in the tank. What do you call this coral? Is it a bonsai?
It looks like an Acropora valida, which is often referred to as a tricolor acropora. It is doing well.
Looks like brown wafer algae. Not as tough as coralline and can become a problem over time. I actually got a sally specifically to eat my brown wafer algae.
