Ok. Since it seems like lots of people on this forum now require personal experience before a posting , I'll take a crack at this. I have a 15,000 gallon outdoor aquarium. I have 7 Arows; 6 silver, 1 blue. My first silver was acquired when he was about 6 months old as a rescue. He was only about 10 inches at the time as he was coming from a 55 gallon with a bunch of other fish. He has been in the aquarium for a little over a year now... He is well over 2 feet in length. I feed him most hikari jumbo sticks along with tilapia and veggie pellets. BTW... All the Arows eat the same combination. I also picked up a rescue with drop eye and gill curl... Fish was near death when I got it. Over 2 years old, only about 14 inches in length and super thin. It would not eat for over 3 weeks! Thought for sure it was a goner... Got it to start out on crickets then eventually went for the hikari. Also the gill curl corrected itself, despite many people saying the condition always requires surgery. This fish has been in the aquarium for about 10 months and is over 2 feet right now. So if you have a big enough environment, proper nutrition and pristine water conditions you will find that your Aro is much more resilient than you think and can not only survive but can actually thrive even if they come from less than desirable environments. IMO... I would not put a single silver or blue in less than 300 gallons. These guys should reach 40+ inches in length so keep that in mind when trying to determine an appropriate environment. They should also live for a long time (10+ years in captivity) so keep this in mind too. Best of luck to you!
