Guys.I have been hatching brine shrimp.They've all hatched and I've bombed a whole lot of them into my tank,of course the chromis dont waste any time clearing them up along with the banana wrasse.However many of them sink to the bottom and land on the rocks.Now my question is:What happens to those that dont get eating?Is it in their nature to keep floating around or do they cling to the rocks and substrate and attempt to survive?
