By the way, how big do Tigrinus usually get in captivity.
Currently, it is measured at 17inches.
I have it in my 180 gallon and i want to know if i need a bigger tank for it to grow more.
Or can it continue to grow regardless of tank size????
As long as you keep the water clean it WILL grow no matter what tank size it only affects the size of a fish when its in extremely cramped conditions or the water quality is very poor and the fish gets stunted
