I’ve ordered them online and had good luck with them. I’ve haven’t had any issues. They do stay super small, which could be why no one buys them. They “disappear” in a large tank and to see the colors you have to get so, so close - and they are pretty shy (they know just about anything could eat them). I like them, but I probably won’t get more unless I purposely keep a desktop nano tank, as they are so hard to appreciate in anything bigger than like 5 gallons, especially if it is planted.
