Keeping Dispar Anthias. Tips?!

[Willito]

IMO and IME, dispars and alikes should be kept in groups of six or more. This will allow them to behave more naturally and feel more comfortable. I had a group of 14 dispars and 8 Lyretail in medium sized tank and it was a sight to see. Having said that, I would never do dispars again becuase they fade dramatically to a very pale coloration overtime. My Lyretails faded too but not as much. Obviously they were missing something in their diet which I could not provide them with and it's not from not trying.

Dispars are peaceful and school very well together almost full time.
Lyretails are much more agressive but don't hang out together as much, and easy to feed.
