Oscar with possible ich?

[joraejay]

My stock is in my 100 gallon grow tank:
3 - Blood Parrots
1 - Red Tail Catfish
1 - Pleco
1 - Austrailian Arowana
1 - Blue crayfish
2 - Oscars

I had ich on my fish before but it was all over the body and the fish were very lethargic. This fungus is only happening on both my oscars and only on their fins but they are very active and eating really well. So I dont think it's ich. Maybe it's stress from the arowana picking on them.

Either way, can anyone help define what this is? I already upped the temp to 86 degrees. I was gonna dose with QUICKCURE but I don't want to do it if it's not ich. I don't want to put salt because of the catfish.

My water condition is:
PH: 7.2
Ammonia: 0
Nitrite: 0
Nitrate: 10

Kinda hard to tell but there def. is something on its fin but not sure if its ich, bacterial, or parasite but........

when in doubt raise the temp and add salt

If you add salt I would cut the dose in half to protect the more sensitive RTC.

Crap! I didn't even read his stocking, I just jumped straight to the picture. Sorry but becareful with the amount of salt used with your RTC as Columbian Shark mentioned!

How much salt should I add for a 100 gallon tank?

I bought some API Aquarium Salt today. I will do a 30 % water change then apply the salt. The package says to use 1 rounded tablespoon for every 5gallon. I'll use 1 tablespoon per 10 gallons and I'll dissolve the salt first.

I'll let you know how it goes.
