Sorry Brian it was more my fault I quickly read what you said. I could do longer 8-10' is a possibility. Also Kaya if I don't think I can't get the pond for it soon I won't get it. I've had to keep a fish in a tank to small before as I couldn't get anything bigger like planned and don't plan to do it again(no longer have the fish found a better home for it). If I can't get him I will just go ahead like planned and then get another one after the pond is almost set up. I kinda want a younger aro(i know not to get them to small) so I can raise it myself and know exactly how it was fed and wasn't kept in poor conditions, so that might be what I do.
i'm sure you can get them like at 4" to 6".. thats a lot more fun.. to raise them from that stage to when they are adults.. yeah but you can avoid the smallish 2" or 3" aros.. they are pretty fragile then..all the best..
