It would be neat if they just instead became little stripey orange and blue...if only!

That's super valid, yes. The taller the tank, the more difficult it is to do shit. My 27 is actually a hex so it's tall and I am just very thankful that it's pretty self-sustaining at this point so I don't need to reach my arm all the way into it.

Thank you! I'd love to see pics of your tanks someday if you ever want to share them. Aquarium friends are very important.
