Even if it is taxonomically considered a different species, it appears so closely related to a Fahaka that it's splitting hairs IMO, considering we're not breeding them.Corvus wrote: It is well possible this specimen is a "cross river puffer", but it still is unclear if the Cross river puffers is a seperate species or "just" a regional color variant of T. lineatus.
So basically, IMO, you have to decide whether or not a Fahaka with a color variation is worth $500 to you.
