I was just wondering what the slowest growing arowana is, and whats the tank sized needed for it. Why i ask is because i've never had one before, but i want one, and want to start with a smaller one (if there is such a thing)
Are you sure? I've heard small afro's grow faster than silvers when raised properly...
There is no such thing as a small or slow growing arowana, apart from one that is not cared for properly. Don't even consider buying one unless you already have a 180g up and running and the potential to upgrade to something larger in a couple of years..
