I ain't so sure.
L191 does have a red eye but darker than this.
How big is the fish on your pic, seems really small?!!
I will rather think at L27 "Rio Xingu " population, shown in the Aqualog under L27b

hi i agree with yann.. if its an L191 it kinda lacks the green coloring.. nywasy your kinda lucky to have L27b bec. i heard that they are quite difficult to get..
Too many gorgeous loricariids
So hard to obtain! Grrr....
Thanks Guys. That was a close, apparently the L27 is double the size of the L191 when adult.
The Growlux does have a UV effect on colours in the tank, my Synos look purple under it.
