[Help me ID this fishes please ^_^]

Hi guys,

Thanks for your replies. a scorpion fish?!

Its actually pretty small, like the quarter size of my finger (or anyones) so i dont think its a grouper. And it is surviving well in my fresh water aq.

EDIT: Okay have found them, the are called butter fly gobies and they have a sting

Thanks for your help guys!

I did ask before buying whether they were suitable, but seller was saying it was Hu die yu (butterfly fish?)

Here it is chilling in its pre tank
