I keep regular blue velvet shrimp and ADORE them, but I've never even heard of blue dreams until just now.
For what it's worth, my blue velvets have bred wonderfully for me and are super entertaining. The little nano that houses them has quickly become my favourite tank to sit and watch.
Everybody is a genius. But if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is stupid. - attributed to Albert Einstein
