The fish in that pic isnt L288 its an adolescent L140 http://www.planetcatfish.com/catelog/image.php?species=peckoltia+sp(l140)&image_id=10882 , L288 is rather marbled in pattern and imo quite boring to look at http://www.planetcatfish.com/catelog/_species.php?species_id=1652. This fish could well be a nicely coloured/ patterned L140 another photo or a dentition shot will help.
