Yeah its a neat place, I spoke to the curator out there over christmas break and they were barely over 2 years old the biggest ones are around 5ft I would say. I've got a ton of pics on my other comp that I'll try to post soon. The tank is close to 80ft wide i would say with a big island in the middle. Shortly before I visited a couple weeks prior the curator told me a arapaima grabbed one of the ducks off the top of the water then spit him out later and that they have had the HUGE red tails take 1 out also. The tank is so big that there are 4ft red tails schooling in groups of 4-5 in the middle sections of water and schools of peacock bass as big as 10 fish or more that I saw. Most of the Pbass are probably in the 5-7lb range I don't think I saw any bigger than that for now. Theres also a 3ft tiger shovelnose in there, tons of huge what look like motoro rays and huge amazon turtles. Its one of the best public aquariums I've ever been to lots of other polka dot rays in different displays, several 2-3ft silver arrowanas, and an electric eel. The only amazon exhibit I've seen that was anywhere close was in Italy last summer, the tank was much much smaller but they had several Tiger shovelnose in the 3ft range, a 4ft planiceps, tons of huge pacu, and another weird shovelnose that I didn't know what it was kinda like a hybrid looking planiceps and a tigershovelnose cross. ~Trent
