To Jeff (or anyone that can help),
I have the same situation as you described. I started off with 4 adult Lettuce Slugs and 1 baby, and literally overnight, am down to 1 adult and 1 baby! There are spiral forms (at least two) which I've been reading seem to be the eggs. While that's good news, I'm concerned about my missing 3 guys! Did you ever find out exactly what happens to them? They can't just disappear! There was one in particular that I grew quite fond of (he was the explorer) and I was afraid a big bristleworm might be responsible (as there are no fish in the tank yet or anything else that could harm them). There are no pumps or areas where they could hurt themselves (the tank is running on the plenum system and 2 Aquamasters

Dear Joe,
In Jeff's first message he did report losing some animals but if you look at his later messages, you will see they were replaced by a successful crop of babies. It is important to realise that most slugs have a short lifecycle, few lasting more than about a year, and many lasting for only a few months. It is possible your 'lost' animals have died. If this is so, then it is is also possible that you missed the dead animal as they rot very quickly. The frilly folds, or parapodia, are only a few cells thick and could easily rot and disappear overnight.

I assume you have the right algae for them to eat? My advice is to keep your fingers crossed and hope you end up with a crop of babies.
Best wishes,
Bill Rudman
