Centrepiece Fish Ideas

[TheAquariumGuy]

I recently returned from holiday to find my Bolivian rams dead (no sign of attack, they were very healthy before i left). I am looking into getting a few centrepiece fish for my 90 litre tank
All ideas welcome.

The tank has a rounded fine gravel bottom bog wood and lots of plants. It contains 9 rosy tetras 2 yo yo loaches a bristle nosed catfish and a single rummy nose tetra I rescued from a friend.

Could do to work out what happened to the Bolivians first really.
 
I would say for a 20g tank that is quite a lot of fish, the Yoyos are quite big fish and the BN creates a lot of waste for a 20g.
