I bought both 2 bottles of 250 and 2 bottles of 500 mg of amoxicillin for my fish tanks, not very often but I can see a film on some of my dark fish knowing that there starting to develop ick and this is the fastest way to cure it, but if I'm gone for long periods of time and if I've missed the starting of the formation of ick then I use the 500 mg, but normally the 250 mg does the job, it's been years since I needed to restock my supply and I have really been surprised on how much it had increased but as all things have gone up in price I'm not surprised, and as much money as I have in my tanks and all my fish I really don't want to lose any of them and this is the cure for it, Thank You for a good product and the ease of getting it. . . . Rex.

What I received is not the bottle pictured (fish moxi). I got Fix Mox 5oo. I guess it the same ingredient, but it looks different than previous purchases.
