Tomorrow I will pick up a tailspot blenny for my QT to enter my 32.5 reef tank. I was going to get a yellow-tailed damsel and the tailspot but my LFS does not have any. They do, however, have Azure damsels. Is it worth it to just get the Azure or should I wait and get the Yellow-tailed? Also, would they be compatible with the tailspot in a 13.5 QT? Thank you!
