Waitei anthias are cool-looking. I have a school of 4 dispar and 1 ignitus. The dispar came in small and scrawny from a reputable online vendor. The only feed that I found they would eat with gusto was ReefNutrition ROE. Once I got them eating that, transitioning them onto Cyclops, Mysis and pellets was easy. (They only eat otohime-type pellets though, as does my 2.5-year-old Hawaiian cleaner wrasse).
The ROE was really very helpful.
I bought the single ignitus when one dispar managed to jump through a teeny gap in my netting and got fried by my halides. The ignitus gets beaten (lightly) a little bit more often than the other females by the male dispar, but she's getting fat and seems to be accepted by the other females. I do think that the ignitus is a little bit prettier than the dispar, although the dispar are lovely.
I like the dispar and ignitus because they keep a tight school formation, unlike squamipinnis and Bartletts. Squamipinnis and Bartlett's are a little beefier and hardier I think though. Bartlett's and Squampinnis seem to enjoy killing each other off slowly.
