But you do know that emerald crabs are known for eating coral if there isn't enough food in the tank? That's why I said that. It's the same with some of the other fish and inverts in the Saltwater tank.offminded said:
And yet for me, I haven't anything but good things come from the crabs in the tank. So I guess it just depends on the crabs you get, and many other things.agsansoo said:
But like I said, I've never had any problems with my emeralds, so don't worry, just keep a watchful eye on it though.Trio123 said:I have found something very neat about these little fellas that you guys probably already know They tear up some hair algae! Whenever a coral (star polyp, zooanthids, or mushrooms) gets hair algae on them I plop them into a tank with just emerald crabs. They clean it incredibly well and the polyps or mushrroom opens right back up when it is put back into it's tank. We have an emerald crab in a tank full of xenia to control the hair algae... so far so good but now you scared me, I will have to keep an eye on him!
Mine eat some of the frozen rotifers that I feed my corals, and it also gets some of the algae off of the rocks as well as some of the extra food that got stuck in between the rocks.mastercave said:what do you feed a emerald crab to make sure there's enough food?
