next fish.

Anthias are a real crap shoot. Hard to keep alive for extended times it seems.

Flasher wrasses are awesome & hardy. They do need some sand to burrow in & it will jump out so a cover is a must.

 

At those prices, they won't last very long. I've seen both fish go for a lot more money local and online. I would think you're ok with the flasher. I would be a bit leary of the anthias to ensure you know which species you're dealing with...some anthias get really big - too big for a 55, some like to stay in groups, some are solitary, some are really picky eaters, etc. The link states a Ignitus Anthias. If what you saw locally truly is that kind, you will probably be ok...however, the link states that they are "easy". I've never heard anyone call anthias easy. I think LFS like to carry anthias, because they are a good "turn-over" product...people buy them, they die, people buy more. I know Hung at Sea of Marvel won't carry anthias as a general rule - he will special order them, once he knows your setup and that he knows that you know how to care for them. They aren't a beginner fish by any means. However, I'm sure there are all kinds of exceptions and variation to the "ease" some people experience. Good luck....follow up with what you decide.

 

flasher wrasses are pretty cool and they are jumpers but they do not need a sand bed as flasher wrasses create a mucus cocoon over their bodies for sleeping. They generally require the same care as the related fairy wrasses.

 

my anthia isn't hard to take care off, i only bought one though. not sure exactly what kind it was labeled as a "pink" anthia

 

I agree with everone else with anthias. Ive been trying to get a group of bartletts all winter, they look alot like the ones that you showed. The problem is they will look great for a month or two and all of the sudden out of the blue they will die for no apparent reasom. The big key ive found to Anthias is to aclimate them extremely slowly. I also had one jump out of the tank. 
As far as the mckoskers flasher wrasses goes make sure you add them all at the same time. I just put 6 in my tank a month ago. My six line killed three  right off the bat then took to chaseing eachother. They are a great fish. I have 3 that seem to be doing good now. I would love to add more but im sure they would kill off any new one's if the six line didnt get to them first. Hope that helps.

Both fish can be hardy. Some anthias can be very hard to keep. Offer a mixed diet. I would also recommend them in a lps or softy tank as they have a high metabolism and require daily feeding if not a couple times a day. I would also say both species are known for jumping
