I was just wondering if any special care had to be given to acrylic tanks after a death has occurred in them. I have two 3.5 gallons that are empty at the moment due to the recent deaths of Rosso and Poseidon.
I don't plan on reusing them anytime soon but I want to make sure that they get cleaned as best as they can so that if I want to set them up for another Betta, that they don't contain any leftover bacterial.
Any help would be appreciated. I don't want the tanks to end up with any residual bacterial that might be harmful to another Betta.
