I have four of these in my 20 gallon tank.
I would like to add a few more fish that are compatable.
I would prefere a similar size and very colorful.
Any suggestions.
Thanks

These are the small Gouramies aren't they ? Even smaller than the Dwarf Gouramies .
You're spoilt for choice and it's down to your taste really .

Small colourful ... Neons ( or more colourful and expensive Cardinal testras ) , albino Corry catfish , black or Platinum mollies ( can get a decent size though ) , Ruby red Platties , Serpae tetras for starters .

Ruby red platties sound good.
Thanks

How many platys cud i put in my 20gall tank with 4 gourmanis already in it.
