UPDATE: so the day after i wrote this my wife went into labor and i am now a "dadda.of.one" lol (there's to you mumma). so anyway in my impatience (and quite honestly lack of time to try and follow up with anything else while I was dealing with the new addition to our family) I started putting in the pimafix and melafix and it doesnt look like it's done much of anything (should've just listened to mumma when she said all that it does is make your water smell funny). The last day of the 7 day treatment would be saturday but i'm thinking of just discontinuing it because nothign looks better. In fact there are more of these random white spots around - it's not ich - i know ich - this isn't that. And it also appears that the tail fins are looking more ragged than before. In fact i just looked at that pic with the one with teh white fuzzy spot on it's dorsal fin and looking at the pic vs. looking at hte fish right now - the tail fin looks much more jagged (btw pimafix and melafix is supposed to fix tail rot).
Lastly i noticed a fish or two scratch themselves on a rock which i didn't see before. whatever it is is moving very slowly (at least compared to ich) so i still think it's early enough to nip it in the butt before it really takes off if i play my cards right.
I'll try to look at more disease pics adn see if anything else rings a bell. Another thing that looks different is that one of the white spots (I'm up to about 5-6 white spots spread out over about 3 of my 15 fish) looks like it might have something protruding it like a worm-ish thing. i didn't get a good look so i'll look again in the morning. but if it does appear that it's a worm or something i'll pay close attention to those pics because i remember seeing several displaying that type of thing.
EDIT: oh yeah one more thing - the main one that i was originally concerned about with the fuzziness seems to have had two changes. the tiny red spots seem to be gone (although I haven't got a great look at him yet) but he seems far less willing to defend his territory than he did before. he's the smallest of the rams but before he wouldn't let anyone get near his area - now he doesn't seem to be so aggressive about it.
First off, Congrats on becoming a Dadda
FYI, teach kids early how to change water in your tanks and you'll never see a siphon hose again until they leave for college
For the more serious stuff: Scratching / flashing is usually a sign of parasites (both internal and external) The problem in identifying which one for you is that parasites are not usually fuzzy but they will leave tiny wounds (red dots) from where they were attached to the fish.
My first thought was oodinium if the spots are white but not as large as Ick however, with oodinium, time is not your ally and it needs to be treated quickly or the fish become heavly infested with bacterial infection and die. So the symptoms fit but the timeline doesn't. (BTW: OOdinium looks like a dusting opposed to Ich which looks like salt crystals.)
Another possibility is that what you are calling "fuzzy" might in fact be a velvety appearance which could be Velvet disease which is a parasite in the oodinium family but does not act as quickly as Oodinium. This parasite needs to be treated with darkness and copper for quickest results.
If the fish are looking more ragged, you may want to consider using Furan-2 which is a nitrofurizone based product and attacks both gram + and gram- bacterias. Short of doing gram stains and identifying exactly which kind of bacteria it is, this is the best general cure. I would also use some form of a paracide prior to the Furan because if you don't stop the cause, the remedy won't work very well.
Obviously, whatever you have been doing hasn't been working as the fish are showing signs of decline ( another clue for velvet diagnosis.) I would strongly recommend starting an antiparasite med followed up with the anti-biotic.
(Now I'm sure I'm gonna get flack for this comment but... Holistic type meds in general work very poorly on most fish diseases. They are good for prevention but once a fish is actually sick, you 've got to go with the big guns. I've had more people kill more fish with doing holistic dips and swabs as they usually damage the fish they are trying to save. Properly medicating and eradication of the disease can be done without ever touching the fish which IS the best way of doing it.
Now, I need to state that "This is in my opinion" but it's based on years (a whole lot of them
) of hands on experience. )
Hope this helps...
