This is a great question!I did a huge cleaning tonight - scrubbing the rocks, stirring up the sand. I'll post an update tomorrow. Usually when I do this, they come back right away.
twilliard, what is the lifecycle of dinos? If I left them alone and they cannot reproduce, how long before they die off on their own? Or are they feeding off something in the tank and can stay alive for a while?
I will add this for my next RN writeup.
The cell itself seems to last less than 12 days regardless of food or light.
My tank will be on day 14 tomorrow and through today no visible sign of repopulation.
