I recently downgraded my 200l tank to a smaller one, only taking 2 clowns, 2 fire shrimp, one turbo snail and about 10 small crabs.
What I didn't know was the I had a larger crab that must have been in my old tank for years attached to some live rock. Somehow he managed to hitch hike into my new tank.
I purchased a blenny to accompany the clowns about a month ago. A few days ago he went missing... I have just done a water chance and knocked a rock over, the large crab in the pictures came running out with what looked like a little piece of blenny skin on him. Is it possible he ate him as it's no where in the tank?
