BUT, some people aim to recreate the fishes natural environment, which, even with the best efforts, is not nearly as "home" to them as the wild because they are in an aquarium to start out with (this applies to large fish btw).

Others, (myself included), aren't aiming to recreate their natural ...

You have to consider peoples goals when fishkeeping.
I can confidently say most people keep fish because they are fascinated by the way they are, and have a genuine interest in them.

A 6x2x2 tank is really only suitable for fish up to about a foot long, maybe a bit longer. If your fish actually gets 2 foot long, I would suggest that you need a tank that is at the very least 3 foot on the shortest side. But admittedly, you don't need to worry about that until it grows to that ...

What do you plan to do when your arowana is 2.5 foot long and is to big for either the 4x2x2 let alone the 4x1.5x1?

Just to clarify, the aro is in a 6X2X2 <---(not a 4X2x2, and the 4X2X2 was intended for the lima anywasy) and is staying there for life. Asians rarely grow past 2', one of the ...

I had a 9" lima in a 6 X 2 X 2 with a 12" green asian.

The green gave the lima a weekly beating. They were ok for a while, then the aro decided it didn't want to share (go figure). The lima is in the process of going to a more suitable tank.

What do you mean "so i'll separate the aro and lima then". Your 20 Gallon tank is not big enough to keep any of the fish in that you have. Yes they may physically fit inside the tank but that is about as far as it goes. Either move all of the fish into the larger tank, get rid of the arrwona, or ...

Well, the aro is staying.

I was thinking of adding 2 more limas to desperse the aros aggression, but i can't find them in large sizes here. The only ones available are 3-4 inches.

So, i'm setting up another tank in the summer, maybe a 4 X 2 X 2, but more likely a 4 X 18" X 2 or something along ...

Hi all,

My aro sometimes lunges at my lima shovelnose. I guess this time it freaked out the lima bad and it busted its snout on the glass.

Its in a 20g Q-tank/hospital for now with about 5 teaspoons of salt. Any input is appreciated.
