If you had my tank,what would you add next and how many? Take a look at my sig to see what i have now. I don't want to add anymore Cherry Barbs or Danios. I think i need some more colorful fish.
I have really enjoyed my Bengal Loaches...One day they'll get too big but mine are not growing fast at all...they are great! They also have great coloration and in my old tank that had some tiger barbs, the bengals and the barbs schooled together...
I love my little ropefish too. She gets along with everyone.
Not sure about compatability with the other fish you have, so check it out first, but here are a few suggestions:
Corys
Rams
Khuli or other loaches
A little Pleco, Rubbernosed/Bulldog, perhaps
Upside-down Catfish
Neons
