For what it's worth, I have raised and bred corns.

Kathy and Bill Love, Corn snakes: the comprehensive owners guide, https://www.amazon.com/Corn-Snakes-C...ks+corn+snakes

IMO, this is the best corn snake book on the market. Excellent bang for the buck. The Loves were among the old pros at keeping and breeding corns when this came out.

Bleach is an old standby disinfectant. I've used it. There are better things now, but bleach is good if the cage is well aired out. Do not use Ly-Sol and Pine-Sol; they are slow poisons. They will kill a snake after about six months of use.

Most snakes do not need to soak in a water bowl. Soaking fouls the water, is unsanitary for drinking, and is likely to induce skin disease, possibly leading to death. A hiding box is better.

Feed enough to produce an obvious bulge in the snake's belly. Feed once every week or two. IMO, one fuzzy a week is too little. One weanling to medium adult mouse is probably enough. Defecation is usually twice within a week or so of feeding.

IMO, snake looks slender but is generally in good condition.

I dislike a screen top to an aquarium. Screen lets the heat go right out the top, and the snake may abrade its nose on the screen. My preference is a home made top of 1/8 inch pegboard. With a layer of paint (well dried), such a top will last 20 years.
