I know I knowwww that's why the tweezers take the snails out and then dump them in the clove oil. >_>
Yeah, there are a ton of stem plants.... my green temple's main cluster just died, so I've got to replace that, but yeah. There's so much java fern and crypt in there that my parents are always telling me it needs weeded, haha. There's an old photo in my albums, stuff has grown since then.
I really should move the otos to a different tank, but it just seems to be working so well at the moment. They scour the glass and plants clean, and I supplement them every so often with an algae wafer. They could be fatter, and I'm working on a way to do that without nastying the water, but overall everyone seems largely content and Robert leaves them alone for the most part other than the occasional short chase and nip.
