Haven't kept orange spotteds, but currently have a few other species -- spotted, pumpkinseeds, and warmouths. Each species has a little different temperament, but I haven't found any to be a big problem. Mine eat cichlid pellets just fine -- they love the Hikari carnivore food sticks and the Tetra Jumbomins. Frozen treats like prawns, bloodworms, silversides, etc are taken with greed. Veggies also -- corn, broccoli, cauliflower, spinach -- come to think of it, I haven't found much they won't eat. Live mealworms are great and cheap. Each species has a slightly different preference. The warmouths for example are much more pisciverous than the p'seeds. I find them a lot of fun to keep, and gorgeous with the right deco and lighting. I have heard that the greens are very aggressive, but have no first-hand experience with them.
