I wouldn't trust it.. Try looking at fleet farm for livestock troughs. they are alot more solid and very reasonablly priced. I've gotten 40Galons for 20$ and those are def cat safe. most of the 100gal + run about 100$ but you won't need to worry about popping a liner/pool side.
cant find any troughts in eau claire so i may have to build a thing around the pool im gunna get to hold out the cats from popping the pool and to hold the pool in so it doesnt bend out or anything
ive never tried a kiddie pool as a fish tank. and the idea sounds cool but there a couple things id worry about.
1) there is no real structural strength to them. something falls on an edge and the structure gives way and the water all kinda drains out. just a thought to consider.
2) i think an arowana is a terrible choice. from what ive read if heard alot of stories of them jumping. Im imaging there isnt going to be a cover over the tank. so you either need to think of a way to cover the tank or id avoid aro's or any other fish that are known to jump
