I have had the Aqualog All LIVEBEARERS & HALFBEAKS for a number of years and although the photography is great, I think that it could be a lot better especially the Fancy Swordtail and Platy sections.
There are a lot of photos of specimens Hifin, Lyretail and Plumetail that shouldn't represent the strains!(Poor Quality) Also there are a lot of photos of the same basic strains over and over.
I hope that if/ when they produce a revised issue that they include Koi strains and consult some experts (not me

) before labeling the strains (there are a lot of mislabeled strains).
Still it is a good book to have.
