Beautiful tiger pack! All the tigers I've ever mixed with my Goliath always ended bad. Keep us updated with their progression and if any aggression occurs. Thanks for sharing!
Yes, you will have more aggression as they age. I had a pack of five and the GATF started to outgrow the VATF by the time they were about 6-7 inches. Good luck. I hope you have a biiig tank in the plans.
