Well I put 200 HBG in the cage this morning, so far I have only found one dead fish, so I think I'm off to a good start. I checked on them just over an hour ago, and they were eating aquamax 500 quite well. I want to thank everyone who responded to my inquiry on the RESxGSF hybrids, I have read through the information that was recommended, and it appears that the percentage of males to females, although lower than the standard BGxGSF cross, is still acceptable if a predatory species is present. It appears the studies done thus far have been more concerned with reproductive viability, rather than growth potential. Does anyone have any info on a program that shows maximum growth attained over a given time period? mobetter, do you think you could talk your father-in-law into snapping a pic the next time he catches one, then posting it here? I would greatly appreciate it. BTW- thanks for the link, not many places have RESxBG hybrids, interesting stuff.
