What did i buy???

[viper1a]

Good day guys and galz,
Im fairly new to this forum stuff, so excuse if Im at the wrong place. I bought some fish for my tank over the weekend, and bough two of these fish,( in the picture). The guy described it as a goby knight, and i knew it wasnt, but ive never seen a fish like this. So being all confused i bought 2. It sticks to the side,and changes colour to black, or green, or white depending on what surface it sticks to, like a chameleon. I havent seen it being aggressive. it just sits around. Its about 10cm long(3inches+-). Please can any one tell me what this is?

Any way of how i can find out? Jeez Im so confused, such a cool fish, just wish I knew what it was.
Thanx for lookin though

I am not 100% sure it is a goby, also sold as a cowfish.. if it is, somewhat agressive as it gets older, it is like a lazy wolf fish. marbled goby is what they are somtimes sold under, they get like 2 feet and are unactive till a fish comes by and BOOM

ps. never go into a fish store with wallet untill you have researched what you want.. not being rude just saying

+1 with angelfish - it's no fun getting an unidentified fish and then learning that the tank/environment you have set up is potentially unsuitable for it - not saying that's your case but some fish have special requirements (like certain food, tankmates, size of tank, etc.) that should be known first.

I think you have a butis butis, also knowm as crocodile fish or crazy fish
