Lake Victoria cichlid population recovering/evolution at work

I'm posting this in the general freshwater fish section as it may be of interest to hobbyists beyond the cichlid specialists. There is evidence that the rapidly-declining cichlid fishes of the rift lakes are now increasing, and scientists show how this speciation is evolution in action today.

The aquarist is one who must learn the ways of the biologist, the chemist, and the veterinarian. [unknown source]

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]

Well, that was a very encouraging read. The introduction of the Nile perch is one of those ecological blunders that really upsets me and it's fantastic to hear that cichlid species are recovering, adapting and even forming new species as a result of predation and environmental pressures.
