Observations of shell dwellers

[cichlidgirl22]

I found something pretty cool with my similis.
The pet store doesn't have shells in their tanks for some reason.
When I bring my similis home, it takes them about 48 hours to figure out they can hide in the shells when they're stressed.
Otherwise, they'll just dart around on the substrate.
It's really interesting how their natural instinct to be shell-dwellers kicks in, even if it takes them a bit to realize it.
