My fish Sheik recently passed on. I am hoping to reuse the 2.5 gallon Aqueon minibow he was in, because I really don't have the money to buy another aquarium right now, but I am wondering... what is the best way to clean everything after the tank has had a dead fish in it? I don't actually know what Sheik had, but whatever it was... it wasn't good. He kept bloating, he lost his color, his fins seems to be turning translucent and basically falling apart on the last day of his life.
I have read that I can boil the gravel and it will be fine to reuse, and I plan on doing that, but... what about the decorations? I had a bridge and a couple plastic plants in there with him, along with a heater. One petstore told me it's not safe to boil the plants or the bridge. Also, how do I clean the tank itself? One petstore told me to use a mild bleach solution and then rinse the stuff until I couldn't smell bleach anymore. Another told me to let the tank sit empty for a couple days and whatever had been in there would die out for lack of having an organism to feed on. Another told me I can put the tank part into the dishwasher and rinse it when it came out and it would be fine.
