My tank is relatively new so I still don't have visible algae growth. I've got algae wafers and blanched veggies in the tank for them; however, they keep sucking on the tank walls. Does this mean that there's some algae there for them to eat that I just can't see yet?
I'm paranoid about them not getting enough food. They will eat the wafers and fresh veggies if hungry enough, right? The past few days I had spinach, peas, and broccoli in the tank. Now I've got a piece of cucumber.
