Well...I have a 20 gal tank here and a 10gal tank back in Minnesota I am picking up along with some of my other stuff. I was thinking of seeing about converting them to fish tanks but here in lies the issue. They were both used for mice in the past and I don't know if I want to use them for mice again or not. I kind of LOVE having mice and my 20gal would fit six mouse girls but that 10 gal can only fit three and it only has the mesh lid to where the 20gal has a lock lid for escape proof mice, lizards, and snakes. SO would it be possible to turn the 10 gal into a fish tank despite the fact it has had mice living in it for about three years on and off. It hasn't gotten as much mouse use as the 20gal since that was my main tank where my colony of mouse girls lived.
Now the last time the 10gal was used was for a sick baby wild mouse I saved and revived then set free. It has been washed with soup, hot water, and bleach so as to kill off anything the baby might have had. It has a standard mesh lid so I would need an aquarium lid instead and there is also the concern of mice chewing up the sealant. What could I get to actually fix that if it did have a leak and first question being since mice lived in these could they be fish safe or no?
