Ranchu will take foods such as Brine Shrimp and shelled peas (which are excellent for constipation). However, “meatier” types of foods should be used sparingly, and very high protein foods such as worms should be avoided altogether. Developed in Japan, Ranchu are very popular amongst goldfish enthusiasts. Similar to the Lionhead, except the Ranchu’s back is rounded downwards towards the tail at the caudal peduncle. Ranchu develop very impressive head growth as they mature. Suitable for indoor tanks and outdoor garden ponds (but provide protection from predators if kept outdoors.)
