Personally, I would say that the 75 is not even enough tank for a mature Jag. Especially a male. A female will require all of the 75, leaving no room for any other fish. A male, will take all of the 75 and demand another 50 gallons to boot. Your 75 is not large enough for a Jag and friends.

Exactly what I was going to say.
