MONICA! You DO exist on the fishforum! See, I do too! haha I miss you already...
As for the sleeping thing...you've seen (or haven't seen) Booger.
For everyone else, my one veiltail, Booger, wedges himself UNDER his rocks to where he can't be seen at all, or sometimes just his tail is poking out and he's nose down. It's so scary! He looks dead! So...sometimes I have to go over and give his tank a gentle shake and say "Don't be dead, stupid fish!" haha Poor little guy. I must bug him, but he makes me worry so much!
