I know, but I'm not tellin ya nutin! Ok, ok, so they strip(cut) eggs out of the female of one species, then do the same with the testis of the male of the other species, there is a special solution that they combine them in, and voila! Hybrid catfishies! Hope this helps. More than likely both parents have to die in order to achieve this, and it's very painstaking to try and match up their cycles so that they spawn at the same time. Only about %25 actually fertilize and of those only about 25% actually survive to go on for food production or make it into the hobby. Of those only a very small number will ever make it to the size of mine!!!! LOL!!!
