Tank size

[Endorite]

I have three goldfish and a rubber nose pleco in a 65 gallon tank. I’m wanting to get dojo loaches and I’ve already made sure that everything is ready for them. However, I’m wondering how many to get. I originally wanted to get three but I’m not sure if my tank is large enough. So would it be better for me to get two or three dojo’s?

I have 5 in my 55 gallon!
