**first fish tank; first post** So I just wrapped up my fish-less cycle on my 29g tank. (got it to cycle naturally in just over a week!) I put "planted" in parenthesis because all my plants are still on their way. I just have 6 marimo moss balls bouncing around in there currently. SETUP: 29 Gallon Tall AquaClear 50gal HOB Finnex Planted+ 24/7 CC LED, 30 in HyggeR Submersible Heater, 200W Treated Tap Water: Amm: 0ppm / Nitrite: 0ppm / Nitrate: 40ppm EcoCompleted Black, 2 20lbs bags QUESTION: I have 6 Peppered Cory's on the way as well as 10 RCS. I currently have a lot of decaying fish food in the bottom of my tank and my LFS recommended I start with the Cory's as cleanup. I just don't know if I should rely on them to do ALL of the cleanup or if I should vacuum a majority of it out before adding them? I just don't know when the food becomes inedible to them. I know I would not want to eat food that has been sitting around for a week. Any input or ideas are more than welcome. Happy to be posting instead of just creeping through the forums and borrowing all of the best ideas for personal use!
