You will find that once they have eaten all the brown algae they will just happily move around the tank eating algae that is hard for us to see but there is food so don't worry, i have 7 in my large tank and they just constantly graze and i don't have any 'visible' patches of algae but they are all fine. You should be able to have your tanks lights on like normal 12 hour on and 12 off with them inside cleaning up.Halocaridina wrote:What happens when the algae runs out? I do not want them to starve to death and crash the tank.odin wrote:That's good news, yeah you can remove the poop if its annoying you but i would probably wait until they have removed most of the algae or you will have to disturb the tank a few more times then necessary.
I have also turned off the lights totally now it is getting sunnier to reduce algae growth.
