Hitchhiker crab destroying snail population!
Recently I have been noticing a decline in my snail population. I would look in my tank in the morning and there would just be empty snail shells on the sand. I thought maybe they were just dying of old age but I was wrong. I've had this black hitchhiker crab (he is huge) in my tank for a very long time. I saw him today eating one of my snails out of the shell. I then looked into his little cave area and he has a collection of snail shells from the snails he has killed. How do I catch him?! He needs to leave now
