For past week or two a few of my RFAs have been kind of bubbly in the middle - almost like inverting themselves to various degrees. Not sure what they want. Been fighting algae in tank, possibly dinos (haven't checked microscope yet).
I'm assuming probably not a good thing. But any thoughts? Photo of the one is probably worst of the bunch. Is worse with lights off than on.
