I'm going to put the Fahaka Puffer in the same tank with my (6) Flagtail Prochilodus, I'll try to post some pics later on this week when i get Fahaka Puffer. By the way, I'm selling my 8" Australian Gold Arowana for $75, i believed it's a female Jardini, but she/he is in top shape really nice (no hold on the head, no mark on the mouth or broken barbels), and i have never allow it to eat goldfish since day one when i first bought it from the pet store. Right now the Jardini is in the same tank with six Flagtail Prochilodus and the reason i'm selling it is because i getting a Fahaka Puffer this week, so if your interested in it and you live in CALIFORNIA (Pick up only), email me khoatran_3688@hotmail.com. This Jardini that i'm selling is really shy and timid, she used to be in the same tank with another Jardini Arowana and they dont fight at all (I was really shocked because the other Jardini is like about a 5'' long), but sadly the other Jardini hopped out of the tank and died last week, she doesn't chase or attack the six Flagtail Prochilodus that i have in the same tank with him, . here are some current pics of the Jardini that i'm going to sell.
