Added new fish, now 2 aren't eating

[djdk]

I have 8 tiger barbs and a pleco in my 29 gallon now. Of those 8 are 4 new tiger barbs. Since their addition, 2 of my tiger barbs are not eating and of the two, one pretty much spends all of his time in a cave hiding. Think it may be bacuase they're adjusting, or are they sick?

Is it the new ones that are not eating and hiding? Did you quarantine them for any time period? How long have they been in the tank?

It is possible that the fish have an ailment of some kind, but with out specific symptoms, it's hard to diagnose and recommend a treatment.
