As a dad, if you don't like to take care of your children alone, you'll be ashamed to see these males – cardinal fish that keep their eggs in their mouths to protect them for weeks after they are born until they hatch. And during this time, these males never eat. (Image from Oriental IC)

The Surabaya rosefish are fish that hatch the next generation with their mouths. Reported on March 29, 2018 (the exact shooting time is unknown) that Nicholas More, a 41-year-old dentist and photographer from Leicestershire, England, photographed a male Surabaya rosefish (cardinal) while on vacation on the north coast of Bali, Indonesia. This male Surabaya rosefish wraps the eggs in its mouth and protects its children until they hatch and grow up. It is said that during the incubation process, these male Surabaya rosefish also never eat. (Image from Oriental IC)
The male fish spits out his eggs every few minutes, allows them to move, and sucks them into his mouth as soon as he senses danger. (Image from Oriental IC)
It is listed as an "endangered" species on the IUCN Red List of Endangered Species. The range of this fish is very limited, and only traces of their survival have been found near the Banda Islands in eastern Indonesia. However, on the eve of New Year's Day in 2016, Qingdao Underwater World has successfully bred the species for the first time. (Image from Oriental IC)
