That’s definitely possible, but I’m not sure because they still look pretty large. I zoomed in close on mine too, but I don’t know for sure about it lol. So I also was thinking - I need to do a water change & remove those rocks. I don’t want them in my tank, they’re too big and problematic. If I keep the sand, do a really good water change, and put in new rock (live or dry), what are the odds my tank will cycle and kill everything?? Especially with these weird bubbles under the sand… I’m afraid my sand has creepy critters under it and will cause a big issue if I remove the rock and replace with something else. Those rocks have all kinds of crap on them.I was using a zoom lens on my phone so they might look bigger...?
