I have recently bought an L-114 on line 8 inches. It cost me and arm and a leg. Anyway I put it in my 50 breeder with 4 size mascara barbs. These barbs are very fast and voracious eaters. My pleco eyes started to sink in and it looked really thin. I feed him NLS pellets and black worms. I could see him eat and he looked fine until about a week ago. I took him to my LFS where he is in a 20 l my himself and he eats and looks good again. I'am wondering if the barbs are not leaving him enough food since they are so fast? My other tank contains an L-25 and the L-114 will definately fight and hurt the smaller L-25. I hate to get rid of the barbs as I like them but the L-114 is rare and I don't want to see him starve out. Any suggestions? What fish do alll of you keep with your expensive plecos? Thanks in advance.
