White Cotton-like Fin

Hi,


My second attempt to keep neons seemed successful, until I noticed the lone survivor of my last batch of neons developed a huge white, cottony looking fin. No other fish shows signs of the same thing. I just put him in a quaratine tank but am unsurr on how to proceed.

 

Looks like a fungus to me. You should treat with some sort of medication. I have used Maracyn successfully to treat fungus in the past, but thet seems really difficult to find anymore. So I would just go to the fish store and look for a med that treats fungus.

 

Thank you!

 

I have been treating with kanaplex, and I can see the growth is a bit smaller, but it says to not do more than 3 doses. Can I use a different type of antifungal medication if I don't see an improvement in a day or so?

 

I found this leaflet, it may help

 

Thank you! I am trying a different medication today after a big water change. The fungus does look smaller

 

Lymphocystis ?

 

Lymphocystis ?

Nope it's columnaris need to lower the temperature to 75 or less and do a water change. Then continue treatment with Furan 2 or more Kanamycin.

 

Oh, wow, I will lower the temp right now!

 

It also seems like his spine is a bit bent, should I continue with kanaplex or go with pimafix?

 

I would stay with the Kanaplex. Pimafix doesn't do anything.

 

I found a male platy with a white thingy on its mouth. He is the betta male though, could it be damage or fungus? He is in the same tank that the neon was in

 

It looks like mouth fungus to me
