2 Small Fuzzy Dots On Fin

[Amunet]

I recently put our danios into the Q tank to treat a possible outbreak of fungus (ended up treating main tank anyway though)...
After the treatment, I did the water change, and was about to scoop out the danios so I could put them back in the main tank when I noticed 2 very small fuzzy white dots on one of their tail fins.
Fish acts just fine, no other spots present on it's body or on any of the other fish... but I don't really think it's nothing.

What could it be?
Don't have any maracyn 2 atm, and we just ran out of the jungle fungus clear that I just used to treat them with before.

Do have some melafix, maracyn 1 and tetracycline left if what I'm dealing with can be fixed with any of these.

Any help would be appreciated
I'd get pics but well.. they're danios, they don't want to stay still long enough to get a decent shot

Use the tetracycline but only in issolation.
Good luck.

what do you mean only in issolation? Like I should take all of the other fish out first and treat the one?

 

[WILDER]

Some makes of tetracycline wipe the bacteria colony out in the filter.

Oh... well it's already in the Q/H tank anyway so it doesn't matter if the tetracycline I use wipes out bacteria or not.

 

[WILDER]

Good luck.

Thanks a bunch once again Wilder!
