I saw these two gelatin like eggs or something else floating around my tank tonight after the lights went out. The only fish I have in the tanks are a pair of Davinci Clowns, a goby, and a boxfish. Thoughts?

Can you put them in a shallow dish with a white background, still slightly submerged, and take some close-up shots?
