so yesterday i bought a couple of these Red Devil Fiddler Crabs. i had a tank all established and ready to be set up for these little guys. i got home and began my research, and found out quickly that there just isn't alot of there on these guys.
i knew going in that they need access to dry land for breathing, and that they are scavangers.
after much research my knowledge has been expanded to they need brackish water to properly survive.
can anyone tell me anything more? does their water need a filter, or agitation? how much water do they? do they actually need dry land, or can i just give them rocks sticking out of the water, or should they have land to walk around on? so on and so forth.
