Greetings, I have a question…. Is this common for small fish to get stuck in the filter drain/vacuum pipe/tube end? I'm confident that my water is fine my ammonia levels are at 0 my Nitrite is less that 0.25. So far my 45 gallon tank is cycling, going on 1 month and two weeks. I do partial water changes as advised, use the recommended amounts of prime, sea salt, no ich, and my water temps are stable at 80-82 degrees. In my tank I have 4 red eye tetras, 4 minor tetras, 5 pristella tetras, 2 angle fish. All groups of fish have been introduced weekly. I have a 'Marineland (Bio wheel) Power Filter Penguin 350' for an 60-80 gallon tank. This morning I found one red eye tetra and one pristella tetra dead stuck to the filter drain. How can I prevent this if possible. There's a lever on the top part of the drain/vacuum pipe/tube. I have it closed all the way. If I open it partially would that help relieve suction from the bottom part of the tube/pipe?
