Mouth-brooder Fish Breeding..

            Mouth-brooders carry their eggs or larvae in their mouth. Mouth brooders can be broken up into ovophiles and larvophiles. Ovophiles or egg-loving mouth- brooders lay their eggs in a Pit,which are sucked up into the mouth of the female. The small number of large eggs hatch in the mother's month, and the fry remain there for a period of time. Many cichlids and soma labyrinth fish are ovophile month-brooders. Larvophile or larvae-loving month-brooders lay their eggs on a substrate and guard them until the eggs hatch . After hatching , the female picked up the fry and kees them in her mouth. When the fry can feed for themselves,they are released.

                Ovophile month-brooders can be bred in the main aquarium because the eggs are produced in the month cavity.However, it is better to separate mouth-brooders with eggs because of their potentially aggressive behavior. There are no special breeding tank requirements others than the usual tank set-up for the species. Larvophile mouth-brooders should be placed in a separate breeding tank because the eggs are produced in the month but laid on a surface where they are open to predators.

Egg-buriers fish Breeding

Egg-buriers
         


              Fishes in this group usually inhabit waters that dry up at same time of the year. The majority of egg buriers are annual Killifish, which lay their eggs in mud . The eggs remain in a dormant stage until rains stimulat hatching.

Spawning tank

                  A peat-moss substrate is one of the best substrates of egg-burying species. The peat moss can be removed after spending and placed in plastic bag to be stored for weeks to mother (depending on the species). A new peat-moss substrate can be placed in the tank for further Spawning. In order to initiate hatching, the stored peat can be immersed in soft water.
