That's like saying I want to buy a tang.
Geniacanthus range from $100 a pair to $10,000 per fish depending on the type. I've had pairs of Bellus and Wantanabai, gadgets had a pair of Swallow Tails; those 3 are ~$200 a pair and thrive once established. My 4+ year old Wantanabai male just jumped kast month, he thought he was a chromis, always in their school.
