Or should I say "red-clawed"?
My snail population has been declining at a rate of one every week or two and I haven't been able to figure out why. Yesterday morning I was observing my tank with just the moonlights on, and I noticed my emerald crab perched on an overturned snail shell. He sat still for a while trying not to be noticed, then he went back to picking at the snail. That little s**t had been killing my snails!
Kinda makes me wonder if he killed my goby and my fire shrimp, and wasn't just scavenging the dead bodies like I had previously thought. I got out the net and cornered him against a rock, then plopped him into a ziploc baggie.
I then left my own little Hannibal Lecter in the baggie to think about what he had done for a while.
This afternoon I took him to LFS and told him what he had been up to. They said they'd take him and put him into a tank with no snails. I thought "Great! He won't be killing any more snails!" He was then dropped into a tank with a few fish. Within a few seconds a puffer noticed him and made a meal out of him.
Wow. I wish I hadn't seen that.
