Is this velvet?

[apex82]

Just got finished with my horror of velvet... Most fish did not show any symptoms other than heavy breathing and hiding. By the time I saw some evidence on body they died the next day or so... Could just be the initial stage and its hard to tell at this point. I say watch like a fn hawk and try to find the wrasse. If they stop eating I would be very concerned. I must have had velvet in my tank for awhile before it broke out as well( same like you, no new additions for awhile) Everybody was healthy, eating like pigs, you know the story. The velvet was brought out from the stress of a mysterious poison. How long ago did you change the rio pump, was it brand new? Only reason I ask, the morning after installing new powerheads is when I woke up to all 13 fish lying on side, breathing heavy and possibly the cause of unleashing the velvet outbreak.
