well bad new guys i went to his previous owner he said he raised him in 150 gallon pond and he was over 4 years old. he eats like a pig and i have another black id shark and he is 16 inches and 3 years old
I have a 20" albino i.d. thats over 15yrs old i got for free when the store who owned him closed. Granted others from this same batch were close to 40" so agreed theres really no definitive answer to ur question. Some always seem to stay smaller while others grow large fairly quickly. Chances are it will take forever to grow, only 2 out of 12-15 from this lfs exceeded 24-36" in 15-20yrs and they were raised in a 500gal.
