lol oh it was freaking me out i wonder how come i never saw them in my old tank because i moved the rock from my old tank to my new one maybe a month ago

yup, good filter feeder for sure. If you want them gone just scrape them out and reduce or eliminate the light that is hitting that overflow box....

yeah I have a few, for a while there everytime I would shut my return pump off and cut it back on some of these would come flying out. Never figured out why like 7 of em would come out every time I would turn on my pump
