White blotch of lineatus wrasse

[ingtar_shinowa]

I've notice over the past couple weeks my female lineatus has been less boisterous and then today durring a water change I notice a light colored blotch on her side.

I'm trying to get a picture but as you all know, fish seldom cooperate. My first thought is a bacterial infection. There is no aggression towards her nor her towards any other fish in the tank.

Size 125g
PH 8.2
Salinity 1.026
Nitrates 40ppm (a little high for sure)

NO3 Zero

Its a mixed reef LPS dominated right now. I've been battling nitrates using MB7 and ecobak pellets. I am running a SRO 2000xp skimmer and I feed a mix of NLS pellets and a home frozen food made from shrimp, scallops, squid, octo, clams, oyster, mussel, cyclopeze, Nori, spirulina, and selcon. No other fish show any change in behavior and all are eating and well.

Most likely injury from a rock.

Thanks for the input. I agree it was either that or from jumping into the net top. Anyways she is acting normal again (bullying the 6 inch black tang for food) and the bacterial? infection on her side is almost gone.
