I bought an expensive small Nem at the expo last year that dissapeared a few days after I put in it the tank. Then I bought a large one from Shack, it's about about 6-8 months old, doing well.
A few months ago I bought the absolute brightest, prettiest rock flower I've ever seen (eBay).
When it arrived I was just in awe but it was very small! It disappeared two days after I had it, never to be seen again!
My quess is that it was in the sand and I vacuumed it up.... An after thought of course!
Or
I crushed it with a rock and killed them! Be careful if you go looking for it!

Maybe my big Emerald crab is eating them? It's about to go, regardless!
