Needed a big fish Tank

Dpiper and I are working on a Fishingtx project, we need to locate a 300 to 500 gallon fish tank or aquarium. or any kind or large portable water tank.
If anyone has any leads please contact us. Once the details are worked out, we will move the info to the open forum.
Thankyou

Randy I'll make a few calls today

Randy. Does it need to be glass? Do you want to be able to see through it or does that matter. I did know someone who had one for sale. I think they wanted to much for it. I can check with them again.
