Please help. Ive noticed this slimmy snotty transparent gel goo grwing on the live rock. Upon closer inspection i noticed there's 3 holes that look a lot like openings for crittersto crawl into. i cant seem to get a decent photo of it. ive tried all kinds of modes on both my camera and on my phone. my phone seems to take a better shot if you play with settings. Anywoos. Help....
