Set up a saltwater tank and get some legal rays. They are WAYYYYY cheaper than freshwater rays and you can get them at lots of LFS. I live in LA and I see 4 inch saltwater pups for 50 dollars. And this is at one of the more expensive LFS in West Hollywood. Plus they are silver and look like sharks...personally I like the way they look better than FW rays. And the California round rays don't grow larger than 9 inches, so your 180 would work.
