Back in the day I don't think this very exquisite fish was around and since coming back into the hobby three years ago I saw them. WOW ! ! ! These are nice. Lots of times you see pictures of fish in fantastic color but the ones you have just aren't the same. Many factors come into play. They got moved and are stressed, the water is not to their liking or they are aren't the best specimens. First thing you do is make sure they are eating good food regularly and that you are giving them a nice clean aquarium. I'm a big believer in species only tanks. Some fish don't like other fish no matter how peaceful or non threatening they may be. These could be fish like that. Good luck with them.
