i myself wont cross them anymore.. only breeding true lines .. and if i cant get pure breeders i wont breed them...
ive got a couple nice ct males awaiting a pure ct female or two .... just havent found any i want yet lol
mainly concentrating on halfmoons now anyhows but i guess its personal prefrence that i only want to breed pures
they are easier to sell ,plus your not filling the nz market with fish with unknown lines, who knows at end of day most of the fish we see have to be started somewhere by crossing some varient / selective breeding process.. you never know what will come out of a spawn
ive never been too much of a fan of pk fighters , ive had a couple of pairs.. one melano black and one pure white but i onsold them
