Is green algae okay on crocea shell?

[plaz]

One of my croceas has developed a thick (kind of slimey) green algae on the upper half of the shell. It could be cyana - although every other time I've had that in the tank it has been red or black. This looks almost like thick phyto. Otherwise, the clam seems okay.

Should I try to suction it off or leave it alone?

Thanks!

if it doesnt seem to be bothering the clam then you could leave it or remove it

might be best to remove it ( if easy enough ) to prevent unwanted attention from algae eaters.

Good point! Thanks to you both for the advice and info!
