Re: NFC: Re: Fishy Behaviour

A possibility that exists in some breeding styles is the 
consideration of parental investment. Somehow, the parent may 
know which eggs are not doing so hot or will most likely not 
survive. They could eat these and concentrate on rearing the 
healthy ones. The thinking may be better a few definite survivors 
than zillions of goners. This is what lots of terrestrial vertebrates 
do, though not necessarily by eating the young. Of course, this 
wouldn't apply to those that abandon the fry to survive for
