I am looking into a new tank (300gal+) for a Silver Arowana (or other) and friends. I am in the beginning stages of research to make this possible.
My first situation is that I bought 5 acres & a modular homes about 3 years ago and and am now getting ready to build a new house on the land. The new tank will be built in the new home. I can not put a tank that big in the "trailer" now as it has a raised foundation not suitable to support that kind of weight. So I have to wait, I am having a hard time with that. So in the mean time I am debating the idea of keeping one in my 150 gal tank that I currently have. But I do not see to much info out there on growth rates. If I purchase one about 2"-6". How long would it take to outgrow the 150 tank? The building should be in place in another 2-3 years. Do I have the time or do I need to suck it up and wait?
My other concern is for the water changes. Most of what I have read tells me to do a 50% water change every week. That just seams a bit much. I have always gone with the mess with it as little as possible method. Do as much as I can in the initial set up to keep from messing with it too much. I have always believed the more you futz, the more that can go wrong. Is there a way to set up to knock that back to say twice a week or once a month, or is that pushing it?
