Fish question?

[Trixiemixie]

I have a 20 gallon tall tank. I have two guppies and one blue guarami, and two platies. I have 2 guppy fry in a separate tank and I will probable keep them there. Anyways, I was wondering if it would be ok to get a pleco for my 20 gallon and if so what kind would be best? And could I get anymore fish? I really want like a type of fish that would really stand out in it.

Thanks

Albino bristle nose pleco, rubber Lip pleco, or a clown pleco. A common pleco would get to big. Common plecos are honestly just waste factories IMO.
