There's cucumber in the tank which he's ignoring and then this morning i put in an algae wafer which every fish but him ate I have a fair amount of algae so i guess he's pretty happy munching on that for now!
Is it and L128? Ver similar to the L134 but they dont have the yellow as much...
NB posted this after eading only the first page...
