Hi, I did a search, but couldn't find much information on this, so hopefully someone will be able to help me? I have had my axies for nearly a year, and was just wondering whether I should be using anything to disinfect/ sterilise the tongs, turkey baster, siphon etc with? I currently only use hot water, but am worried that I could be transferring infection to the tank, especially as one sadly died yesterday. I did a large water change, but is there anything else I should do, as I don't know why she died? I am worried that the others might catch something. Thank you
