Nope, never wondered. I wonder what big rich, victor, Vincentwugs biggest aros were? I bet they are under 48”. Tell me their filtration isn’t up to par and the tanks are to small. 300 gallon is still a lot better then the 55 gallon it was going to end up in.Did you ever wonder why a fish that easily hits 4 ft in nature, hardly ever reaches its full potential in aquariums?
Could it be they are normally kept in too small spaces, where water quality quickly suffers, and they get stunted?
