I'm guessing ich but spots seem raised on powder blue... just got these fish last week and they seemed to be doing great until I noticed this last night...would it be safe to dose tank with paraguard as I unfortunately don't have a QT tank set up any longer. My parameters are all spot on and tank has been well established for over 4 years... I do have a few bubble tip nem and a 4 year old 2 foot snowflake eel in tank so I'm concerned about dosing with paraguard...any help would be appreciated from those that may have had similar problems and used this product...thanks in advance..
