I was just cleaning my glass hoping to get more junk caught in the
skimmer. At least, I figured out one nitrogen export that works. :-)

And, I noticed exactly what you're talking about above. I bought 3
conchs awhile back and never saw them again. I do have one oversized
hermit that seems to be evil to snails, perhaps I should move him to my
new tank and add more clean up crew.

It's time for another purchase.
