Still a mystery. Since this is a new aquarium, I havent done any water changes yet. There's no fish, so there's no reason to change water. Also, Im using remineralized RODI
water, so the hose I used to fill this aquarium is different from the one that I use for my other two tanks.
I saw it again as I was rearranging some rocks and plucked him out. Assuming he was alone (which I cant say for certain) this tank will be snail free for just a little bit longer. Plants should arrive in the mail on Wednesday or Thursday... so we'll see how much longer.
