like that. Mostly because many people do not want to here it.
First, putting your landloving monitor in the bathtub is a bit like putting your goldfish on the floor for a small walk(flop) while you clean their tank(humor). It most likely will not kill either the goldfish or the monitor, but its not fun for them either.
For V.albigularis, deep water means its flooding and its time to seek high ground like finding a nice sturdy tree or find the Ark. Swimming water is for such species as niles, waters, mertens, even mitchells. Many of the indo species are good swimmers, but do not seek water.
A landloving monitor only seeks water to soak if its dehydrated. So if your monitor is doing that, then fix the reason its dehydrated. Whoops, and if its too hot, they will seek water to stay cool. Both of these things are not good things.
I understand your doing the best you know how, and soaking is very common, but so is dehydrated monitors.
I am sure many here will help on how to keep your monitor from getting dehydrated to start with. First understand, houses are normally horrifyingly dry for reptiles. If you make your house humid enough for reptiles, then your house would rot and mold. Second, air movement passes this dry air from our houses over the monitors. This is the problem. Monitors, most all reptiles can only expose themselfs to fairly humid air. Think Fla. in the summer and all the reptiles. Or Az. in the monsoons.
So take it easy, have fun, and find out ways to not soak species of monitors that are not semi-aquatic. Good luck FR
