I am currently in a Marine Bio class, and as part of this class I have to setup and maintain a 30 gal saltwater tank. I already have 2 hermit crabs, 2 snails, 1 perc clown, and 1 velvet damsel. The other day our teacher said he would like to see at least 3 types of inverts in the tank once he grades them. I was at my LFS looking at crabs and shrimp. They had these little crabs called "red crabs". The are cheaper then the shrimp so I was thinking about getting one. My question is will the crab try to eat my other fish or inverts??? Would the crab be a good idea to put in the tank??? Thanks for any help.
