Yaaaay. So so far, I have two options
A school Rummynose and a
School of zebra danio with a krib or apisto (my best lfs tends to have kribs but not apistos, but I could always check again)
OR
Just one convict or jewel, whichever they've got
I'll have to ask my partner what she'd prefer, obviously one option is considerably more expensive and time consuming with quarantining and all. Thanks for the advice you guys!
