as for the aggresion matter i havent found that it makes any difference, my ct spawn had dad in and he ate most of the eggs anyway, the resulting fry that made it actually did seem to be a bit more aggresive then my lastest spawn, ft and hm cross, they are all still in the same 20 gal togather and only one seems to be a brat, and he got removed last week and jared, they are now 8 weeks and the remaining fry all seem to be pretty cool, all are mostly the same size but a few are huge and a few are small, but not too much aggresion, at the same age the ct spawn that had daddy were all tweaking out and ripping each other to pieces. ?? maby its just single fish personalitys? and really bettas arnt puppies, puppies understand what it means to be alone, loney, upset, scared, sad, all that kind of emotion, bettas,, well realy most of them like to be by them selves, so how much interaction with dad is realy benificial anyway?
