Any possible way to feed these guys just once a day? or do they usually succumb to starvation like the sunburst anthias?
Did you get the .5mm pellets? They are very small said:NLS 1mm sinking pellets (mostly "Marine" but occasionally I'll switch up and do "Thera A") are my staple food for big fish, small fish, and everything in between (including occasional target feeding of LPS and anemones). I buy the 5lb (I think it's labeled 2.27kg) buckets, and use that to fill smaller containers I keep out by the tanks (keeps the loss from the occasional spill, splash, whatever down).
I feed frozen as the occasional treat, but mostly just while I'm trying to get new fish trained over to the pellets; I've found that if I gradually mix in some pellets with the frozen, and they see other fish eating the pellets, they usually figure it out pretty fast. (Of course, some never do, and some never eat anything, but that's another story or two).
Outside of that the only thing I feed is nori sheets for the herbivores to graze.
At the moment, the only anthias I have are Dispars. I've had others in the past, and they've all pretty much done well on the pellets (most anthias that do well in captivity eat like pigs once they get eating).
At the risk of a slight thread derail, I'd also mention that anthias are on the list of fish (along with angels, butterflies, tangs, and most bigger fish) that I'm real likely to suspect of parasite (fluke) problems from the get-go, and I'm liable to treat new ones with prazipro at the first sign of cloudy eyes, reduced appetite, whitish poop, or just general principles. The few times I've hesitated to do this I've ended up regretting it.
