Tarantula water dishes

[Poec54]

They would still grow bacteria even though they aren't pourous? The glaze seals the clay so nothing can get into it. Thanks for your comment, I'm just trying to clarify.

It's not the glaze, it's the fact that they're constantly full of water and sitting in organic substrate, occasionally being fouled by feces, boluses, and drowned/decaying animals (crickets, mites, etc). It takes some thorough scrubbing to remove whatever takes up residence in there, fairly regularly. If you use a soap/cleaner, you have to make sure that all of that's removed or it could be lethal to the spider.

Placement of a hard object like that is important, and it has to be away from the sides, as a falling spider can land on it and rupture it's abdomen. People not realizing this, along the importance of having deep enough substrate in their spider cages, run a higher chance of losing their spiders to falls.

Permanent bowls look decorative, but there's certainly downsides to them in spider cages. They're more practical for reptiles, and that's a bigger market anyways.
