This is an awesome Red Hump Geophagus! They get about 6 inches and are semi aggressive. One important thing to include in their aquarium is soft sandy substrate that they can sift through. They grab mouthfuls of substrate and sift through it for any food particles. Red hump geophagus enjoy meaty foods such as bloodworms, tubifex worms or high protein pellets.
