I have just taken up this hobby and are looking for advice please.I have found myself a supherb aquarist retailer and have purchased a jewell korall 60 tank and have cycled this for 6 weeks,had water tested[all ok]and introduced 6xzebra danios and a betta siamese.What i would like to know is what anyone would recommend to go with the fish i have already purchased[all doing very well] and numbers.Sorry for what might appear a silly question
