I was thinking about getting some baby hi-fin banded sharks but I plan growing them up a bit in a tank so they will be at least 6”-8” long when they go into my koi pond; I also plan on getting a 220 gallon aquarium soon that I could move them to grow koi in, but the tank I have now is a 78 gallon and I am worried that it may be to small to grow them in. Because if they grow fast I figured I would want to wait until I get the 220 and finish the pond before I get them, then I would just grow them up with my koi and simply start some goldfish in the tanks I have now ( the largest being the 78 gallon). So I was curious actually how fast they grow? I tried doing my own research but I can’t seem to get a straight forward answer, just that they get big and are best suited for large ponds, which I know.
