Returning user after a six year break!

Hello fellow MFKs!
I had to give up my 240 gallon aquarium for financial reasons a few years back. Now that my situation has gotten better, I would like to start fresh again. But I wanna go bigger this time! I remember all the useful threads on this forums that helped me when I got my first stingray! I even had a 'monster fish keepers' sticker on my tank and I think I still have the shirt, but I'm not sure.

I'm thrilled to be back into the hobby. I'm looking to buy a 500+ gallon aquarium setup (8' X 4' X 2') so if any of you guys out there know of anyone, PLEASE let me know. I've been searching on craigslist for a while now with little luck.

Previously in my 240, I had a motoro (still a juvenile about 14" in diameter), a black arowana and a few chic lids.

This time I want to keep a pair of polka dot rays and three black arowanas, although I've heard that they are very hard to come by these days.

Again, I'm extremely excited to be back here!

Thank you! So I had three aquariums at one point. A fresh water (240 gal) a salt water (60 gal) and another mini salt water (30) gal. Here are some of the rare specimens that I've had

My 240, notice the MFK sticker at bottom right?
