Help With Identifying Fish Please

I recently bought two of these, and they were labelled as gara-garas in the shop. They are very good algea eaters.
I have been browsing the forums and reading the various posts on the differences between algea eaters, but to be perfectly honest I have got myself totally confused!
Could any of you experts out there please put me out of misery and let me know which fish I have here?
Many thanks!

Wow-that would be cool if that's what it is.

nvm id ont know lol..

I'm quite sure that's a young Garra Bicornuta - see that linked thread for a little more info

Also: Species Summary.

Thank you all so far for your replies to my query. I'm still not entirely sure, but I have had a closer look and I can see a blue spot just above the left and right pectoral fins.
I seem to remember reading somewhere (think it may have been somewhere on this forum) about an algea eater with these same blue spots, but I can't find the information anywhere now.
