Fish bruising!

[briley91]

I have an exquisite wrasse is showing a bruise on its side after being QT for 3 days now with no meds up until a few moments ago i dosed some Prazi. I’ve been feeding Mysis with selcon and some formula one flakes but making sure to not have flakes floating after 20sec or so of feeding. The water was is only a few days old as well. Salinity is 1.020 and I have a sponge filter going and a tunze wave maker. He does have a Midas blenny as a tank mate but are clashing in the slightest. He’s very food responsive but is hanging out at the bottom of the tank now.

Did the spot show up suddenly? It could be from one good bite from the Midas blenny.

Has it been eating some mysids?
Are you testing for ammonia?
