Keith - seems an awful lot of fish for a 60 litre tank, even when you've removed the neons and plec. I foresee a few problems...
The Rams, being cichlids, will get territorial - in a 60 litre with so many other fish this might be a bit difficult for them. Watch out for any signs of stress - darkening of body colour, clamping of fins, listlessness etc
Also, you will need to keep on top of water changes as you have more than double the normal stocking level for a tank that size IMO.
