ALFish

Hi, help needed please. I'm setting up a bigg tank (170litre) I will be putting a 2 Angle fish, 1 starlight pelco, a 3 little noens. The tank with have a large driftwood piece and a few plants. But my question is that what, fish would be a good addition ( and that are great colours) as the tank is in the main living room and everyone will see it. So I'm wanting it fun to look at. Thanks for any help😉
