IMO... anthias is definately not a good starter fish to keep even for the hardy ones.... Anyway hardy ones are squaminpinnis aka lyretil anthias, rubizonatus aka tri - colour anthias or truncatus truncate fairy anthias..... All of these anthias cost ard $10.... Anthias are schooling fishes and they should never be kept a pair... if you tank is small one will do(anthias do very well even when solitary) but if your tank is bigger a group of one male and many female can be kept together......
BTW anthias need regular feeding(3-5 times a day preferbly) so if you can provide that for them, suggest you dun try them out......
