So I bought my first snail this past weekend and put it into my new 20H. This tank had previously been fishlessly cycled...but somehow the nitrites have skyrocketed...I've been doing water changes furiously, but they don't seem to be going down much. I'll give the newest test readings in a few minutes...I just did a water change. But I came home and the snail was floating on the surface with bubbles on it...thought for sure it was dead...but I took a closer look and it's still alive...but it looks deformed...and seems to have left some slime on the wall that it touched. I'm worried the nitrites might have gotten to him? Should I take him out and put him in a fish bowl and see if he recovers? Suggestions?
