Total loss, new set up

[Felix]

Suffered a total loss on my Red Seax Max 130, lost matched pair Clowns and Royal gramma. So decided to do a 50% water change, remove the living rock. just letting it cycle at the moment. Not had a problem for getting on for 8 years the clowns were my originals and the RG was getting on for 6 years. lost a flasher wrasse a while back and decided just to keep the three as they seemed happy in the tank.
So my big question is?
Do I buy more Live rock? if so where is good these days used to buy from Steve at Red Sea then Blue world and Big Als mainly for food as the fish seem happy and there is a limit to how many you can have in the 130 litres.
And of course Fish, I know not ready for them yet but apart from a pair of clowns and a gobi or a scooter what are members suggestions and who has a good rep for fish (if you work somewhere please disclose).
Thanks Felix
