Very nice stock. For that stock, in the medium/long run, I would add more filtration to make sure enough beneficial bacteria is at equilibrium with your current stock. Question, how long have you had this 180gall with this stock? I am assuming you recently added many of these fish as your water looks incredibly crisp yet (IMO) under-filtered for this bio-load. I myself overstock my tanks & do WC 2x/week @ 65-70% per WC. Check your water params if you have recently added many of these fish as it may mini cycle & you know rays are extremely sensitive to ammonia/nitrites.Again, nice fish!
 
^^^^ That. Is. Awesome! Geez, I need something else in the tank with my silver. He's all alone in my 180.

Back to the original question, I do 15-20 gallons 3-4 times a week. I also have (2) FX5's and a biowheel 350 running. I would do more, but my fish is only around 12" long, and he's all alone, so I'm not dealing with much of a bio-load.
