I designed one of my tanks around my Pictus Catfish. I love these guys. If you want a solid hardy catfish that wont grow too big , get a few of these guys . If you do buy some , make sure you have a silk net to catch them , other wise the sharp barbs will get caught in the net. Trust me , you don't want that to happen.... if it does . I used little scissors to slowly cut the threads away from the hooked barb.
