(Other members of the genus Nothobranchius)

ADULT SIZE: 5 cm

WATER CONDITIONS: Not critical

TEMPERATURE RANGE: 22-28 C

FOOD: Feed Nothobranchius guentheri predominantly live foods

DISTRIBUTION: This species comes from Tanzania

SEXUAL DIFFERENCES: Male fish of this genus are brightly coloured; females are smaller and a dull grey/brown in colour.

AQUARIUM CARE: Nothobranchius guentheri is one of the most attractive members of the genus, due to its bright colouration. Males can be aggressive when females are present, both to the females and other males. Best kept as a hareem in a small species tank, or as a spawning group with plenty of individuals in a larger tank

BREEDING: This is a typical annual substrate spawner, which should be spawned over peat, which is then partially dried and stored. Eggs develop at different rates, but usually most are ready to hatch after 3-4 months.

Other Comments: We have a lone male Guntheri and he is in a community tank along wtih Danios, Endlers and Guppies. He is extremely aggressive and was viciously attacking the other fish. He was introduced to the tank with the Guppies at 6 weeks old and he got along with them fine until age 4mths old. He then suddenly turned extremely aggressive to all of the fish (60ltr tank). So he is now in his own small tank. I would not suggest putting Guentheri's in a community tank.
