Have you actually seen one of these? I got one and it had great pictures but it isn't really about anything in particular and I binned the one I got as apart from the great photos there was nothing really of interest just bits and pieces about 'breeders n keepers', so I couldn't complain as that was what it was called. I wanted a book about all aspects of keeping shrimps and this wasn't that. I believe one f the experts has written a book and I wish I bought it when I saw it on my suppliers website as it has also gone now.
I recommend seeing one before buying though as it MAY not be what you want/think it is????
I wonder why that would be? I'd think an oak is an oak wherever it's growing. Perhaps a result of me leaving them in the sun? It's not a big issue, once they get soaked they become pliable and soft it's just a head scratcher...
AFAIK, only crystal reds. FWIW, Rob at Flip imports the vast majority of his stock. Price of success, I suppose. He can't breed them fast enough to meet demand. He's very open about this and a great guy to deal with. But I wouldn't buy Caridina as imports when they can be had (much) cheaper home bred from a hobbyist. Mischlings might be a good way to go, you'll usually get a variety of black and red crystals F1, depending on what they were bred with. And they tend to be a little hardier like tigers, though still more fragile than most Neos.
