Review on 🥮 SunGrow 4x4 Inches Floating Feeding Ring for Goldfish & Smaller Fish - Ideal for Flakes and Floating Fish Food by Tamara Simms

Does its job well! I had no problems sucking up against the wall and it matches the feeding hole in the Aqueon's tank cap almost perfectly. I also like that it moves with the water level, it's very well designed in that regard. My only issue is that food that doesn't go in the hole sits on the top rim and gets messy. I have to make sure I clean it (every time I do a water change). I also have problems with my larger fish because they are all sitting in one place. So my 4 platys will eat the food and my tetras and other mediocre eaters will have to wait until they tear it apart enough to start swimming. I will still use it as my main reason for this purchase was that every time I add flakes it is used up immediately, half of it swims straight to my filter and the water flow pushes all those flakes down quickly into the filter . Water (which caused a lot of wasted/wasted food). So it also helped keep my tank a little cleaner in that regard.
