breeding notes

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.

Fishkeeping Facts and Tips

Avoid tankbusters! Too many tropical fish stores sell small fish that will continue growing until too big for any home aquarium. Rehousing can be very difficult indeed. Avoid species such as the shovel-nosed and red tailed catfish
