Because I have had plenty of Mana both in my own private selection and in the aquatics dept I used to run, and all the pure Jags are much much more mottled in colour than this. They also tend to be silver where as he is yellow. Also the Jags have a mottled line down there sifde where as this is a straight bar like a Dovii has.
Also the fins are blue tinged. Now I know before anyone tells me that no 2 fish are identical and colours vary. But this I still dont believe is a pure bred Mana, He has a wicked set of teeth on him as well. (again I know Jags have a decent pair as well)
I am happy if it is just a mana as It means I dont have to worry about an even bigger tank.
