I have never heard of a GT X has anyone out there ever had any, I think this is a beautiful fish, I was thinking of maybe a GT X Texas, don't know if its possible, post pics if anyone has a GT X.
i have heard (i don't know if it is true) that GTs can only cross with acaras. they look similar so i don't think that you would gain anything if this is true. maybe someone else has tried.
