Cross post | Need advice on wrasse compatibility

[JonathanV]

Hey guys! I’ve been lurking on r2r for awhile now and this is my first time posting here. I was wondering whether or not a McCoskers flasher wrasse would be compatible/fine in a 20 long? I’ve done a lot of research on this topic up to this point as it is my dream fish and I understand that while the recommended volume for this fish is around 30 gallons, vertical swimming distance is by far the most important factor in making swimmers like wrasses comfortable in the tank. Also, I’ve seen in some threads where people have kept smaller flasher wrasses in 20 longs without any problems. With the 20 long spanning 30 inches and a decent amount of rock work and caves to break up territories, I was wondering whether or not it would be adequate to keep the fish not stressed and to not be cruel towards it? If not what would be some other recommendations as I would like to add some swimming/movement in terms of livestock to the tank? I will also be keeping the bioload low if I am able to add this wrasse to the tank.
Thanks so much!
