If you haven't already, I suggest you Google the fuzzies. I found lots of articles when you first posted this.

According to what I read earlier today, you can have up to 6 fuzzies in one 100g tank, but 5 must be females.
So, as I said earlier, according to the article, you could have a pair no problem in your 80g.
Only issue I see is if the male bothers the female constantly or not. Then you would need a second female.
Basically, he said fuzzies are OK in groups in our small environments
