I recently converted my tropical 65g tank to a goldfish tank. Right now, I have 2 goldfish: an oranda and a calico ranchu. They're about 2-3 inches right now. I also kept my mystery snail. Back when I had my tropical tank with angels, I didn't think too much about my snail because I know the angels aren't always picking for food and I often saw my snail digging around the substrate and eating other dead plant matter. However, since converting my tank, my tank is now bare bottom and only has anubias and driftwood. My goldfish are, like all goldfish, always looking and eating whatever food they find. I'm just concerned for my snail who I haven't seen eating even though I will drop half an algae wafer or a shrimp pellet in front of him. But he'll just move around it or not notice it and then I'll leave for a few hours and see that the food is gone because of the goldfish. Long explanation aside, does anyone have any tips on making sure their snails are eating when housed with goldfish? I also have an additional question: I've done some research and it seems I could fit 5 goldfish in a 65 gallon. Is that advisable? I have an Aquaclear 50 and a Penn plax cascade 1000 cannister filter.
