I acquired 4 citrinellus at bout 3" from Jeff Rapps about 3 days ago and they are very darty/skittish. They are constantly on edge darting about the tank. I bought these guys because I wanted a personable fish but so far they are disappointing me. They are in a 125 with 2 salvini who are also shy and 6 darty silver dollars which are getting on my nerves. I swear these silver dollars panic when you blink. Is there anything I can do to bring my midas specifically out of their shell? I can't even get them to eat because they are so darty. Are they just getting acclimated?
