bad idea...I like that fish so much you've sold me on getting one! There are two in Montreal near me at about 19.99$ CDN each, no idea of the sex though.
In your opinion how do you think a 3-4 inch dovii would fare up to breeding pair of jags (8" female and 10" male) and a 12" arro? If not it could always go in my 75 gallon to grow out a little.
I have plenty of hidding spots and the tank would be a starter (125 gallon).
I'm building a 300 Gallon and the arrowana will probably be traded or sold.
