I've always liked Mata Matas. The only thing is...they can just sit there and get pretty boring. At least that's my experience. But I love the look and the smile.
Just for you...here's my "little" pair hatin' life cuz I put them in this bin while their tank is being cleaned. The larger one on the left (female) is pushin 30lbs. They're fed on shiners and 10-12" shad I catch at the reservoir dam.
