I found what I think are a couple of eggs on the glass that I'm hoping you folks can identify. My nassarius have been laying eggs like crazy and I've watched them doing it so I don't think these are theirs. The only thing in my tank ar two clowns a cleaner shrimp and a cleanup crew that consists of Dwarf ceriths, Florida ceriths, nassarius and nerites. The nassarius eggs are about half the size of this and white, also sort of a cluster and a whole bunch in a group. There are only two of these one at each end of the tank and they're both about the same size and yellow.
