I have a 30 gal
nano reef, which was an upgrade from a 12 gal
nano. With the upgrade I added an additional 5 hermit crabs to go with the five I already had and it seems lately all they want to do is try to kill each other for their shells.
I'm used to seeing a couple at a time get tangled up, but quite literally, all eight visible hermit crabs this evening were all over each other fighting. I hate to see them fight, and like it even less when they try to kill one of my snails! I've tossed a few extra shells in the tank, but they don't seem interested which leads me to my next question. Are there other crabs that I can consider that won't spend their days trying to kill one another but do the same job as members of a clean up crew?
Thanks for any suggestions or ideas, it would be appreciated!
