i did a second water change yesterday. About a 10% water change. I cleaned some of the detritus off the rocks. And I found another snail that fell upside down. It must have been there for days, I thought it was dead until i flipped it over and it came out instantly and immediately starting eating algae. It looked starving...
I am finding coraline algae everywhere now. Its growing on the sand, the glass, the rock, the back of the tank, i even found it on the skimmer in the back, i was surprised it could even grow there since there is next to zero light.
