Plecos and plants

As another option, I'd also recommend Pakistani Loaches (aka yoyo loach). You see them all the time, not just ground dwellers either, they swim a fair bit around mid tank height.
Here is a pic of mine from my low tech tank. I need to get some more actually. They would be amazing in a big group.

Love the pakistani loaches - have had these many years ago. Slowly creeping up in species size here.....

I know at least some loaches eat snails. What about shrimp?

Apparently not allowed shrimp in my state, so I don't think it wil be a problem for me, unless I head out with a dip net this summer to find some local Paratya sp.
Caridina are banned....

I have hillstream loaches and panda garras. I think both are cool, but you will see the panda garras more often. They’re very active and will swarm my hands when I’m doing maintenance. I have to put a mesh over my pump or siphon when doing water changes because they’re so curious.

she says their body shape creeps her out.

Think of them as little micro- manta rays..

I also recommend Panda Garras. Amazing algae grazers, really fun fish!

Love these fish but don't see much algae grazing.

Yoyo's will decimate shrimp, Hillstreams pretty shrimp safe but may get some shrimplets almost by accident. Dwarf Chains are shrimp safe until they get closer to mature and then will take out all shrimplets.

Yeah basically Kings and Devils Fish Friends are my 2 best options. I think DFF has true Hillstreams.
