Is it true though that the majority of fish wont cross breed anyhow??
Yes in general however there are many exceptions to the rule. Lake malawi cihchlids for example seem to be the worst affected due to simularitys in a very heavily vast amount of species still being discovered. People cross breed these then sell them to pet shops here then people are charged a lot of money for crap. I got caught out paying $70 for a sulphar crested peacock that turned out to be a mongrel and it really pissed me off. Then onto the american cichlids,, you cant or its very hard to get a pure red devil, midas, green terrors these days etc etc because someone wanted colour or didnt give a crap.
Cross breeding in the wild does happen but nothing to the extent that man can do. Breeders will cull thousands of fish to get that right fry or even sell the rubbish they cant get good money for as a lower grade as in the cases of Flowerhorns, blood parrots(a lot of these fish are dyed too, very cruel)
You would really have to get advise from someone on what to cross breed and how to do it and depending on tank size,, you can make a colourfull colllection , just not like a neon,guppy type setup colour wise with wall to wall fish.
ANyway mate if you really wanna have mongrels in your tank and treat them just as humanly as other fish(Im not one for cruely keeping any fish) then I guess thats up to,, I wont condone it ever though
