Why do fish put babies in their mouth?
by
These species of fish shield their young by using their mouths as a protective shelter. This unique kind of nurturing care begins at the time the eggs are fertilized. In many cases, after the eggs have hatched, the fry continue to use their parent’s mouths to hide from potential predators.
Mouthbrooding is when fertilized eggs are carried and incubated in the parent’s mouth. Rather sophisticated for parental care in fishes, it may have evolved from lack of nest sites, predation or habitat invasion. It occurs in more than 53 genera of fishes.
What type of fish are mouth brooders?
Species of fish defined as mouthbrooders include cichlids, sea catfish, cardinalfish, Bagrid catfish, pikeheads, jawfishes, gouramis and arowanas. For mouthbrooders, parental care starts when the eggs are fertilized, and some even extend their offer of shelter after the eggs have hatched.
Mouthbrooding is a strategy where parents keep eggs (and sometimes newly hatched fry) in—you guessed it—their mouths. There are three types: paternal, maternal and biparental mouthbrooders, depending on whether it’s the father, mother or both who store offspring in their mouths.

After the female releases the eggs and the male fertilizes them, she gathers them carefully in her mouth. The eggs will remain inside the female’s mouth until they hatch into fry. Additionally, the female will allow the fry to enter and exit her mouth for a period of time after they hatch due to protective concerns.
Why are my cichlids eating their babies?
It’s a great start for the young fish, but it’s extremely tiring for the mother cichlid, who can’t breathe properly or eat during that period. The new study shows, however, that the suffering moms can counter that by consuming some of their young, a behavior called “filial cannibalism.”
