Rearing Fish Fry, Lake Malawi National Park. This is Lake Malawi in East Africa. It is 00:00:00
almost as large as Belgium. The lakeside is littered with boulders that have rolled down 00:00:08
from the steep surrounding mountains. The fish in the shadow of these rocks breed their 00:00:14
young in a very unusual way. This fish is known as Cichlidae, a dominant species. 00:00:21
During the breeding season, the male Cichlidae removes sand from the seabed with his mouth. 00:00:29
He is making a breeding bed for a female. A female Cichlidae enters his nest. Her colour 00:00:35
is very subdued compared to the vivid male appearance. The female Cichlidae spawns her 00:00:42
eggs and puts them into her mouth right away. She doesn't actually eat these eggs but hatches 00:00:49
and raises them inside her mouth. An attack, the mother's mouth seems to be the safest 00:00:55
place to be. This is a large catfish locally known as Kampango. They are also raising fry 00:01:03
in their nest within the rocks. The baby fish are now about two centimetres long and protected 00:01:12
by their parents. A Cichlidae is swimming around them, waiting for a chance to prey 00:01:19
on the baby Kampangos. A Cichlidae mother is letting her babies out of her mouth. It's 00:01:25
amazing how they grew up inside her. But this world is full of danger. Parents can never 00:01:33
rest until their young finally grow up. Back to the Kampango nest, a female Cichlidae is 00:01:40
being chased away several times but keeps coming back to the nest. Slowly and carefully 00:01:48
she is releasing her babies from her mouth. Now the babies swim away from their parents 00:01:55
towards the Kampango parents. Here their babies are safe from other Cichlidae. Kampango can 00:02:01
also benefit from this. Baby Cichlidae fry divert attention from the Kampango babies. 00:02:09
The Cichlidae parents are busily chasing enemies away from the mouth of the nest. Here the 00:02:17
two species can co-exist in harmony. Unique ways of rearing and protecting their young 00:02:24
have been created in a world where the strong prey on the weak. 00:02:30
