The Red Shoulder Severum Cichlid, which is native to the Amazon, is a trusting species that will sometimes take food directly from your hand. To keep this fish content and happy in their home, provide them with a tank of 20 gallons or more where few plants are present and there are some large rocks for swimming about; water should be soft on the bottom. If you want to make your fish even happier then consider adding other big cichlids into their school! They’ll enjoy eating frozen foods too like freeze-dried bloodworms, ocean plankton (including tubifex), flakes, and pellets that attract cichilds naturally.
