AWWWWWWWWWWW!
I think we should have a contest.....
CFC, Paul, Tik, Cane, should we try that with the rays?
Now I know one of my girls might allow that her tummy to be rubbed.
Although I am not going to film it, just in case I have to dial 911
This behaviour MAY actually be beneficial for the fish, removing old dead "skin" cells, potentially any parasites present, and fungal spores adhered to the slime coat. I would imagine any damage done to the slime coat would only be superficial and would be replenished quite quickly. How is it any different from when a fish moves substrate; particularly gravel, around or swims too and fro between plastic, or even some real plants for that matter, etc. Besides which, if the fish was unhappy, or it was in any way painful, it just wouldn't do it.
As for it being cute, I'm not too sure - interesting maybe, but not cute!
For those worrying about the slimecoat.... Christ, if they were that fragile I don't know how fish would survive at all!! The slimecoat is more durable than that and quite thick in goldies, I don't think it's anything to worry about -- maybe if your hand were completely dry when you handled it, but that's pretty much impossible to accomplish with your hand in the water, eh?
Very cute video, that guy is lovin' the attention!!
We have a huge (12"+) porcupine puffer at work, and an equally large clown trigger. The puffer LOVES to have his back scratched, and the trigger, while mean as the devil, enjoys having his sides rubbed. In fact, the only time your hand can be in the water without him at least thinking about nipping your fingers is when you're scratching him. We used to have a little porcupine who'd sit in your hand and let you pat him, he was the friendliest fish I've ever seen and begged for attention constantly.
