Absolutely looks like snail poo to me too!!!
Also, has anyone ever had a snail that was happier in a small tank??
Of all my snails... there is one... my VERY FIRST snail ever!! He seems so much more active and happy in a small tank alone.. when I put him in the 15gal. He never moved once!
Then had to move to a 3.5 for a fungal infection in the 15gal and he still wasnt himself. He started in a 1.5 gal.. which is where I have him now by himself... and he is more "himself" than I've seen since moving him the first time!!!
Is it better to just leave him be in a 1.5??
I constantly changed his water and can do it again!! If that's where hes happiest. I feel I should leave him be...
But has anyone else ever seen this???
OP?? Anything like this??
Edit: he is a SMALL magenta 'mystery snail' about a quarter of an inch.... if that.. very small.
