What types of tank mates do you keep with pictus catfish? At the big box store in my town I've seen them with both Old and New World cichlids (I know not the best metric). What's the smallest fish you've kept them with? I'm guessing they'd chow on neon tetras or guppies but what about larger, deeper bodied tetras like diamond or rosy? Are they best kept with South American fish or are they adaptable with Central American cichlids? I'm not currently buying any, just researching.
