Maintain these water conditions for optimal health and vibrant colors
Lake Kurumoi Rainbowfish is a compact, red-orange rainbowfish from the Lake Kurumoi region of New Guinea. It is a better choice for keepers who want colour and movement from a peaceful group rather than a single large centrepiece fish.
Use a planted aquarium with open swimming space through the middle. These rainbowfish show better colour and confidence when kept in a group, with clean water, moderate flow and calm tank mates that will not nip fins or outcompete them at feeding time.
Choose Lake Kurumoi Rainbowfish if you want a rare-looking rainbowfish with manageable size and peaceful behaviour. Livestock is sent by licensed live-animal courier and covered by our Live Arrival Guarantee.
