I am at work right now. I'll try to get some pics/videos/details tonight. I am going to stop by petsmart on my way home and grab a couple of platys or something else cheap.
Just one thing.. The tank is about 128g filled to the brim plus a 75g sump... Bioload/water quality might become an issue as the fish grow large, but if you have a topoff system, and modify it to drip a few gallons per day this tank could be stingray heaven
Looking good, and I agree with the rest... more pics!
kev hit the water quality right on.... amazing looking set up... also the D/I is not recommended for rays usually leads to unstable PH.... you don't want excessive shifts in PH.... otherwise that is a stunning setup...
