No to the temp swing~0 on ammonia~I have seen these teeny tiny little elongated snail looking things hanging from 1 of the snails~I've also seen them hanging on the glass~they are very hard of shell.
Describe the shape, size and color of the snails please. You could get a Tuxedo Urchin, would add some neat life and color to the tank. Might have to sell it off after the algae is gone though.......
