Success keeping achilles

[Willito]

6 foot tank is nice but not a must, mine is in a 4 footer. This is what I find works good:

-Should be one of the first tang in tank
-strong water current
-Run UV before and after adding new fish for a few weeks
-quarantine for the purpose of eating and not disease control

Mine is living with a powder blue and amongst others for almost two years. Prior to this, I lost 5 due to to improper quarantine.
