- No lake in the world contains such a diversified and distinct community of cichlid fishes as Lake Malawi - more than 800 species have been recorded.That 800 that evolved from only two species.
The cichlids are among the fishes best designed to adapt to living in a tropical lake. All Malawi cichlids are endemic to this lake.
There are even cichlids you just can find on one certain spot in the lake, like Pseudotropheus saulosi 05:14 at Taiwanee Reef.
Apart of that sometimes more than 70 different species are to find at a single location.
The most important factor that gives cichlids an avantage in a new lake is their ability to adapt rapidly to a new environment.
Therefore you can find several types of feeding specializations.
The Aulonocara species 00:50, with their large opening on the head which looks like colored patches, feeds by "listening" to the movement of small crustaceans in the sand.
The fin biter Genyochromis mento 01:21 has the nasty habit of feeding on the fins an scales of other cichlids. Many chichlides have notched anal and caudal fins, souvenirs of encounter with G. mento.
Nimbochromis livingstoni plays dead and waits for small fish prey to swim by.05:30
But the majority scrape off algue from the rocks or digging for invertbrates in the sand.
But there is common behavouir - all Malawi cichlid, apart from the non-endemic Tilapia rendalli, are maternal mouthbrooders. That means that only the female takes care of eggs and fry.
In the average three weeks of brood care the fry lives in the mouth of their mother. If they get to big, the fry will be released.
The lake Malawi is 560 km in length, 75 km in width and 705 m deep.

Home to the best African cichlids!
Every African cichlid keepers dream right there!
Fish are amazing!
Really nice footage! Saulosis, linni and livingstonii mamas with fry - no they aren't behind every rock so these are really valuable shots 👏
Thank you very much! You nailed it! 🙂 I have a malawi fish tank and i always wanted to dive there. It was amazing to see them in their natural habitat and if you know about the cichlids behaviours and its a real pleasure to observe them
Incredible footage!
Thank you so much! I really enjoyed diving Lake Malawi!
Omg such a beautiful place. How is the current under water, does it feel still or is there a lot of current?
Most of the time and places is no current. The only place with current was the spot where the Ps. saulosi are to find
Great video.
Thank you 😍
Beautiful. What a majestic place.
It is indeed. So many colorful cichlids and activity
Awesome footage!
Thank you!
Amazing video Alexander. I've become really interesting in the story and history of Lake Malawi and would love to dive it one day. An honest question for you though. What is the risk of bilharzia when diving at the lake? Was it something you were conscious of or is the fear overblown?
If i remember and understood correctly, the risk is when you get in the water unprotect, means bare skin, or walk bare foot at the lake shore, both only in certain areas. We were told that scientist do a constant research on that and know the spots well. The places where i stayed was no risk. But the lodge manager gave us bilharzia pills as we left, just for the case. The pills are much cheaper in Malawi
Awesome!
Tolles Video
Danke schön!
😍😍😍👍👍 Great video.
Thank you very much!
Lake Malawi is a 40,000 year old. A Malavi Cichlid live for 6-10 years. So, there has been a lot of generations of cichlids for evolution to work on.
Thanks for your informative comment!
I'm always curious on how they film in these lakes...aren't huge crocodiles and hippos on the perimeters of these african lakes,beatiful video thou....!
Thank you 🙏🙂 we didnt see any hippos or crocs, altough we visited many spots around the lake, but we heard stories from the lodge owner who joined us on this trip about crocs in some areas. Now and the they spot one/some, but they dont survive very long....
We swim everyday Lake Malawi is quite safe
awesome +globaldivemedia
Thank you! 😍 your comment!
Are cichlids edible? Seem like a good source of abundant protein for the locals.
yes they are, and there are also fishermen on the lake, altough only the bigger cichlids make sense. locals overfished a certain cichlid species, that in turn caused or spread out Bilharzia. this certain fish namely feed on snails which had the Bilharzia worms. So the snails increased and the worms increased. thats how things are going...
I thought OBs didn't occur in the lake.. 4:19
Me too. I thought they are a breeding form
OB werer said to be at about 0.1% of Lake Population. So they were known in the wild,just rare.
Big difference between an MCAT and an OB Peacock. MCAT's are generally rare to see in aquariums but they are found in Lake Malawi. OB Peacocks are a hybrid, which are everywhere but NOT found in Lake Malawi.
@@stayathomecichlidmom3579 The video referenced shows an OB Estherea( Red zebra) M.cat typically refers to Labeotropheus Fuelleborni OB.Im not sure if OB Fuelleborni have wild specimens. You could be right about that. But I dont think the question was referring to any peacock,though you're correct about them being hybrid hobby species only.
@@TheKiaiKid I know a few people that I can ask about the OB Fuelleborni, that will know and I apologize, I just assumed OB Peacock,since that's generally what most are referring too.
