Yeah, one for a dovii, one for a peacock bass and silver arowana with a shovelnose catfish and some stingrays. And I think you can get the stuff to cast acrylic, I think they even sell it in hardware stores, and I looked up casting acrylic sheets and it said it could be done. I also have thought about taking a 120, dismantling it, and using the 2 long panels as viewing panels for a plywood tank, so it would be a 6'x6' tank with 2 viewing panels (one in front and one on the size), but I don't know if it can handle the pressure or not. To be clear, this is all in the future, not at the moment, I'm just thinking ahead.
