Rectangle Trigger with possible Ich and a skin gash?

[NTP66]

So, my newly acquired Humu is currently in my 10g QT, where I have started tank transfer (first transfer is Friday). I wasn't able to get a real good look at him yesterday when he arrived, because I wanted to acclimate him in a dark area.

Today, I turned on the lights in the bathroom (yes, my wife LOVES that our downstairs bathroom has been a fish health system for the past 2 months ), and noticed two things: 1) a white dot on his tail fin, which I'm going to just assume is Ich, and 2) a white gash on the left side of his body, right behind the fin.

I'm planning on continuing tank transfer to deal with what I believe could be Ich, because that was the plan all along. With regards to the gash, though, do you think it's okay to leave as-is for the time being and just continually monitor him? He ate right away, and continues to eat just fine. He also swims around the tank normally, and grunts - everything I'd expect him to do.

One tank transfer has been completed, I was going to move him to my 29g QT and dose PraziPro for two weeks. I'm just a little worried about that gash, and am not sure how I should prioritize his "illnesses". I know triggers are hardy as hell, but I certainly don't want to push the envelope.

Here are some pictures, though they will prove to be pretty useless, I'm sure (bad lighting, subpar iPhone 5 camera):

keep the water as clean as possible and keep him well-fed...can you post some better pics? wish he was in and going into a larger tank...

I'll try and get some better shots tomorrow. It's hard because he's always moving and so damn fast. He's about 1.5", FWIW, and will go into a fresh 10g QT every 4 days until tank transfer is finished (3/31), where he will go into the 29g QT, with my 90g DT being his final destination.

I didn't want to risk keeping him out of water for any extended period of time, so here's the best shot I could get this morning. You can see the gash to the right of his fin.

I see that many reefers panic as soon as they see a white spot . How is this fish breathing if it normal and you can only tell when he is sleeping with a flashlight . I wouldnt transfer most external parasite infestations start slow [ except for brooklynella ] and you have time to treat. Moving him around will stress him more and lower his resistance. I keep fish in qt @82 F with copper power. This will cause the parasites to advance to the free swimming stage when they are most vulnerable to copper, salinity should be low 1020 to 1015. is sufficient .The tank transfer method is based on removing the fish to avoid reinfestation from the free swimming parasites. YOUR FISH WITH ONE OR TWO SPOTS IS NOT YET AT THAT PIONT AND IF COPPER IS IN THE WATER IT WILL KILL MOST AND EVENTUALLY ALL THE FREE SWIMMING parasites over tne next three weeks .If the disease progresses and more appear on the fish I raise the water temps to 85F and areate well .FEED FEED FEED its a trigger he should have mysis, krill ,clam, shrimp, clam, garlic and vitaminC. good luck
