Barking catfish ???

You can get them to grunt by catching and holding them. Be careful, because they will use their pectoral fins to trap your finger up against their body spines. I know both of those things from personal experience, because I had to transfer two from my 29g to my 125g. Very cool fish, even if they don't spend much time in the open.
 
I have a striped Raphael but he just hides all day, and I never get to see him. How do I get him to roam the tank?
The more hiding places he has, the more likely you are to see him. More available cover will make him feel more secure, so he'll be more likely to show himself. But you shouldn't expect to see him much except at feeding time and occasional glimpses.
 
sharks bark too i know this has nothing to do with it but when people catch sharks out deep sea fishing alot of them make a barking sound when they come out of the water, its just a quick burst of air being gulped down
