Clarkes clown fish Behavior

Hi Everyone,

I recently purchsed 2 clarki clown fish and put them in my 50g aguarium, along with 50lbs of live rock that has been sitting there for a year.

The fish kind of hang out (and do not leave) the back corner of the tank, and sometimes lie in the sand. I have had them for 2 days now, and they seem to be feeding fine.

Are they just a boring fish, or should I be concerned?

 

Clowns wil act real strange at first. Give them a few days. We have one that sleeps on top by the overflow.

Do you have any other fish in the tank?
Is your water testing ok?
How long has the tank been running a year with the rock?

 

Thank you for your reply. The tank has been sitting for a year with the rock in it. The chemicals are all very low because nothing has been in the tank. The salt is at 1.024. There are no other fish in the tank yet.
