Discus sick w/cotton like sunstance on wound
Hi Everyone...Shortcut here. As you will see I'm new to the Forum, as well as a newbie w/freshwater fish.
We have a 144 gallon tank that houses Discus, Pink tail chalis, loaches, neons etc.
Last week I noticed a lot of movement in the day I see white cotton like stuff on the wound. After observing, it looks like our Discus could be rubbing it off.
Any ideas on what I should do? I tried to net but was unable to.
No other fish is having problems or has any signs of the white stuff.

Thank You very much for your time!

Thanks Herefishy!

I did read the referenced material prior to posting. Just not sure which disease it is...3 or 4 diseases have the same symtoms.

I do appreciate you answering my inquiry...You were the only one.

You say the fungus appears cottony. I would treat with a good quality fungucide. Another good product that I like to use is Pimafix. Combined with MelaFix, they are the staple of my medicine cabinet.

I look forward to learning more from the members here. I know you and other moderators have probably seen these and similar questions over and over. herefishy. thanks for interpreting my question.

Picture of Discus sore- Not sure if I did this right

Is that him/her?

You are talking about the pink spot by the pectoral fin? That's an odd place.

Watch carefullly he isn't getting picked on. If he is, give the culprit a time out in another tank while he heals.

I also use Pimafix. What I like about it is that it is natrual. Whatever medication you decide to use, just watch to see if it gets worse.

Also looks like they are spawing....wish my discus would "get in the mood"....very nice fish. Good luck with it.

Thank You for answering. Showed this same photo to my Aquarium guy. Said"No worries. Won't spread, will get well. He gave me Anti-Parasite Medicated Fish Food by jungle. It is noted on front of bottle w/PRAZIQUANTEL Is this a bacterial infection? AT the beginning of the week, white cottony stuff was on wound. Don't know if he/she scrape it off.

Still going to buy what you and herefishy suggested.

Typically the white cotton stuff is a fungus, and is normally treated with some form of anti-fungal fish medicine. Sounds like these guys have you on the right track. Let us know how you make out!
