Done daily water changes for the last three days to be on the safe side.
Get some replacement fish at the weekend.
Going to leave the very temperamental Rams alone....taking suggestion for some tank mates!!
Please don't get any new fish for a while until you are completely sure that the tank has matured properly and their won't be any more disasters. If you think it might have been an ammonia spike then it would be cruel to subject more fish to it. After a fortnight more then you can start to slowly restock with more confidence this won't happen again and what's a couple of weeks to wait compared with possibly killing more fish.
Please also bear in mind that more fish mean more ammonia and potentially more algae so waiting on stocking fish is good for the eventual health of the tank and plants too.
