If you want evidence of the gigas zoodiver is talking about look in his albums, also the thing i said about the mekong not being able to support a 1000lb stingray was just me getting wound up as i still doubt their existence but yes the mekong could support such a fish if it existed

Pictures all over the place confirm that arapaima gigas grow much larger than the claimed 2.5M in this thread. Several in my albums are 3 M plus.

Why do I think they grow as large as I claim? Because I've seen them.

I have also seen many self proclaimed "keepers" housing them in terrible conditions more than I have seen them housed correctly. These sub-standard aquariums/pools lead to unhealthy stunted animals. When 80% are kept wrong, suddenly 80% are showing sized that are un-natural. Suddenly, the 'normal' sized fish (3M or more) are becoming the 'freaks' only because keepers are not allowing them to grow correctly.

I fully agree, Just look at the amount of them in tiny tanks on youtube. I have seen many threads by zoodiver, arapiamag and others showing huge arapaimas, biggest i have seen in person was 11ft and the aquarium keeping it had to get rid of it due to it growing too large, im not sure where it is now but they had only had it for 4 years when they got rid of it and it was still growing. I have every faith that the arapaima get as big as zoodiver and anyone else who truly knows about these claims.

you really think they will fufill their potential in tanks like these:

also the pima in the above video is only 2m so think of the tank size.

that one had to be rehomed.................and do you think anyone else has a large enough tank or an aquarium will take it in, i doubt it and it will probably die prematurley no where near its potential size

Those are young one in that pic from DWA: 6 or 7 feet at most. The ones in Omaha's exhibit are larger than those at this point.

Guys,

There is a very large exhibit (rainforest) in Siam Paragon in Bangkok, Thailand. Check out this link http://www.siamoceanworld.co.th/ (click on virtual tour then floor plan). There is info on it in wiki also.

They have a quite impressive size arapaima in there. I have contacted them to get the size of the exhibit and the size of their resident arapaima. In addition to paimas they have a mekong catfish (huge ones too) together with RTCs, pacus and that sort of giants. I am trying to locate the photos of my trip there ...

Check it out on youtube (there is a glimse of rainforest one) - unfortunately ppl tend to focus on sharks and such http://www.youtube.com/watch?v=4TaSSrhMV6k

Wow... I wish I had a large enough tank and wallet to truly care for and breed those crazy huge stingrays out of Thailand... that would be incredible.

Just for a point of discussion, the text from the information sign about arapaima at the Dallas World Aquarium (the largest Amazon basin freshwater display in the world) reads as follows:

"Arapaima gigas can grow up to 14 feet (4.3m) and weigh up to 400 lbs (180kg). Often seen gliding near the surface of the water, this air breathing fish surfaces every 10 to 15 minutes. They are endangered due to over exploitation and habitat destruction."
