I've posted before and asked about my dojo who is doing well. I was wondering if it is okay to mix yo yo loaches with a single dojo loach.
I've read many different website and they all tell me different information. So I was wondering if you guys could help me out.

I have a 20 gallon tank. I keep the water at about 74F. I know I will have to get a couple yo yo loaches. So I know the tank size will be pushing it. I wanted to know what you guys thought before I did anything.
