So im new to saltwater. Ive had planted tanks and even have a 45 gallon ciclid tank now. Just so recently decided to take the plunge into the ocean.. I have a 10 gallon nuvo compleatly basic setup. Still in the cycle phase only had the tank up for a week but when adding live rock i found a crab. Im fairly certain hes a gorilla crab because hes deep red with so.e bristles and black pinscers. Real small though. I just dont know if hes really that and if i can keep him for a reef tank. Id upload a picture but dont know how at the current moment..
