The right plant eating fish for my Nano?

[Harpo]

So Caulerpa is bad for the tank? Also, how do I lower my nutrients w/o killing ,my snails and shrimp. In above comment turbo snail was mentioned but I have 4 and if they do eat it, it's minimal.

You're better off picking it out as best you can once a week and work on lowering nutrients. You should be able to eradicate it in a couple months.
