Give me your Secondary / Side / 'fun' / single-species tank ideas!

[Macbalacano]

I have been thinking about setting up another nano for fun - but not necessarily as another mixed reef, but something more specific. I've seen some cool tanks over the years: Clownfish Harem & Anemone tank, Seahorse tank, softies only, NPS only, etc.

Love to hear others ideas or please share what you've done if you have one of these tanks!

Scallop tank for Lima shrimp. Or if you can get your hands on the colony-dwelling snapping shrimp that form colonies with a single queen and then different castes of workers, like ants. Also seen a lot of berghia nudibranch breeding tanks with farmed aiptasia. White spot anemone shrimp with their nems are also so fun to watch, they feed off the anemone but wont damage it to the point of it becoming ill

This is exactly what I'm talking about! So many ideas and all sound like a lot of fun! Possible to make a little money on the side too!
