Hi guys, I bought a fire shrimp 6 days ago and he seems well, eats very actively and usually stays in the top right corner of my tank. Just today I noticed these tiny white spots on him. I know these have bigger white spots as a pattern, but I don't think these are them. Inverts don't get that 'white spot'? thing, do they? I should add, the back wall of my tank has them tiny white curl like things. I can't recall what they're called but they grow like white curls and he's usually right upto that wall, so could it just be that on him? And if it is, will it harm him? Pic below.
