Yesterday I spotted the matisis shrimp and it was in the rock my octopus has been hiding under so today I thought my octopus was out of his den because I could se strait through the hole but when I lifted the rock up the octopus was under. Stupid me so I looked at the rock and there it was 3 clusters of maybe pin head sized eggs or so It looked is that to small ? But I put the rock back knowing that if I put it is fresh water the eggs would die. The mantis shrimp still in there a pissed of octopus and a cluster of eggs any advice? Not good on my behalf but still what do I do?
