Re: Want fry to grow fast with better survival? Use circular or ellipsoid tanks, not square

very strange result.
I am not convinced of the result. I don't see any logical reason, from an evolutionary point of view (Darwin evolution), why a fish would grow faster in an elliptical aquarium. For me, this result should be taken with great care, there are surely some biases.

Re: Universal model of skin colouration patterns of Pseudoplatystoma

It's very interesting. Because an extrapolation is plausible. We now know that the coloring and its patterns are dependent on few genome parameters. And that they are often linked to the pressure of the biotope. So that this is surely extrapolable, for all fish. And what is most wonderful is that ...

Re: The development of tactile social interactions in Corydoras aeneus larvae

This impact is enormous. Because to separate the fry from the parents (nursery aquarium), you will have future corydoras, with out of phase social behavior. The social, interactive and tactile aspect is very important for corydoras. They need a behavioral model (parents) very early (Learning by ...
