I would say it has pros and cons.I've seen some pretty amazing Hybrids Carpetdro Chahoua/crested It gets tricky when these animals arent steril(sp?) get introduced into the hobby and bred.
Personally I don't mind as long as its done in a responsible manner...

A few weeks ago I came across a Hybrid forum that has pics of various hybrids.I must say there are some cool hybrids out there
