I have never brought any, all my research was done on here. I am going to pick up a fish index type book at some stage. chek out the store on my site for a huge selection
The Borneman book is very good, it is expensive but well worth it IMO.
The Reef Aquarium by Delbeek and Sprungs is the most expensive, that is usually around £50, I got money knocked off with amazon because I had some loyalty points off my credit card to use.
yep mate..reef invertebrates by calfo and fenner and the conscientious marine aquarist by fenner are good to look out.
two good little id guides are what fish? a buyers guide to marine fish and what invertebrate? a buyers guide to invertebrates by Tristan Lougher and any of Ronald L Shimek's pocket expert guides are worth a look !!
