Clowns and crabs

OK, I'm up to a 20 g, lots of live rock and I'm getting 2 clowns-tank raised. My question is do I need an anemone to keep them safe from predators?
Meaning my arrow crabs. I've been reading that the clowns like to sleep in the sand. Or should I get rid of the arrows? I kind of like them for the worm clean up. Or should I just get rid of the bigger ones?

 

You do not need to keep an anemone to successfully maintain a Clown in captivity! I would think twice, however, about keeping an Arrow Crab in your reef tank as they are scavengers as well as predators and their have been numerous horror stories regarding them! I would think about returning the Arrow and purchasing another inhabitant to replace it!

 

Thanks for the advice, I was already leaning towards getting them out as they are very aggressive.

 

Move out crabs. Trade in for small BTA anemone.

 

they definently woud go after small clowns but once they get big they are perfectly fine.my female clown would attack an emerald i had.

 

I would get out the arrow crab.. But, think twice about getting a anenome, I had a bta that got quite large and was beautiful. But it moved around a stung alot of my corals.. Lost 2 leathers, including the one that is in my avatar...

 

Thanks for all great advice, I traded in 3 of my 4 arrow crabs(one I couldn't catch) for an anemone, here's a pic.

 

I agree with the guys/girls, if you have a reef tank the arrow crab is a no-no. They look cool but are not "reef safe". BTW, I dont think that condy anemone is going to host clowns, at least mine never did. I dont think thats a BTA.

 

Thats what I get for trusting the expert at the LFS, he told me that anemone was very easy to keep and would host a clown after some time. Could anyone tell me what kind of anemone this is?

 

what kind of lights and what kind of clowns do you have?
