Urgent Open wound

So dismourning my butterfly wasnt eating, and ate little last night. and when i get home from work today i notice it has a open wond on its underside, and alittel on the side. Check all my Perams. Ammonia 0 Nitrate 0 Nitrite 0 Salt is 1.023 i havent noticed any rubbing or anything. Only thing thats in the tank is butterfly and 2 Chromis. What can i do?

 

Treat with Melafix possibly in a QT tank.

 

Feed a little more often with a quality food. I don't know a lot about freshwater fish so I don't know if there are freshwater vitamins. For saltwater fish I would say soak the food in vitamins and HUFA's.

If the wound is deep, this product is amazing. biobandage - Google Search

 

Ok i have sum of that. Notices lack of activity and sorta heacy breathing, rest of body and kills looks normal no spots and gills are not red. Maybe just rubbed on a price of rock wrong?

 

how long have you had the fish?

hope it'll be ok. and if it wasnt a rock perhaps a crustacean attacked it? emerald crab attack? (my emerald will attack a fish if it pecks at it)

 

this is its 3rd day in tank, i dont have any crabs that i know of and just base rock with 3 very small peices of live rock.... I havemt seen it eat much withing the past day and activity was lowered, i dont have any crabs or crusty's at all. why im worried its a infection or something. when i can home from luch about 5 hours ago it wasnt there, now its there when i get home its the size of a pinky nail

 

Any help? phone pic is bad but

 

anyone?
