Those are are only practical in very large enclosures and only if the feature is very small. They tend to raise the humidity too much, and increase mold / bacteria in the enclosure. Garters get in them and divert the flowing water onto the floor too.

They're OK for amphibians or rain forest insects, climbing lizards, etc. but they don't work out too well for garters in limited spaces.

If you're only using that yellowish basking light, try adding a full spectrum or white light florescent tube. I find it makes a big difference in their activity levels and appetite.
