Long ago, I used to keep a French. I feel they should be in a tank that is at least 30 inches tall but ideally 36 inches tall, and at least 96 (but preferably more) inches long and preferably at least 30 inches deep but preferably 36 inches. But they are a magnificent fish. If you have the appropriate tank, I recommend them. Your 96x30 will work but he will make that tank seem small. Ate out of my hand.
