In the top corner of my Biocube I just noticed these white squiggly lines. It’s on the glass cleaner and up the corner to the waterline. I have a pair of Darwin Clowns but have never seen eggs placed in such perfect overlapping squiggly lines lol. Does anyone have any ideas? Trying to add the pic but not having luck.
