inverts

One of my Malaya shrimp. Just molted the day before.

smaller Amano shrimp- I can still tell the younger ones apart by size, but they are quickly catching up to the older trio.

I think all three of my zebra nerite snails are male.

quite a few times now I have seen mating between the orange tomato nerite and one or another of the zebras- but never between two zebras- and the position of the snails is another reason why I guess so. Except I don't know how reliable that information is, where I read it. But the tomato nerite is my oldest one now- appears to be slowing down- and if new nerite eggs quit appearing after, then I'll know.
