I'm really pleased to see your blue plakat spawning Sam and he looks fantastic. I would breed vt in a flash but the age old problem is that while you can get pure vt males in the shops which have come in to the country there is no guarantee that the female you are buying from the shop is the same tail type. The last time I tried I ended up with spade tails so goodness knows what the female was but I would guess halfmoon.
The same goes with ct, I have never yet seen, myself, an imported ct female in the shop which means any around must have been bred locally
One thing to remember about breeding fighters is that potentially one spawn could give you 300 fry which means a lot of water changes, good food, tanks, time and money to get them to grow out unless you either want to stunt their growth or cull significantly.
