Damsel fish are pretty hardy and cheap but keep clear of them because they will take over your tank. These are a list of good starter fish:
Chromis range from about £5-£10.
NOT TOMATO CLOWNFISH THEY ARE TOO AGGRESIVE.
Clownfish range from about £10-£65.
Goby's are slightly harder to keep than chromis and clowns and they range from about £10-£35.
