Please help, sick fish?

2 of my clownfish are sick, and I don't know what they have as their symptoms don't seem to be specific to one disease.

Tank info:

I have a 65 gal tank, it has been running for a year. Some months back I upgraded to a 90 gal and moved most fish into there except for a pair of percula clowns, a couple damsels, and some inverts I couldn't catch.

Since getting the 90 I don't really do much with the tank, I just didn't want to tear it down and I wanted a second pair of clowns so I kept it, but it takes care of itself, never any ammonia, nitrites, or nitrates (and the sg is 1.025 in case it matters). No new fish have been added to the tank for 9 months but none were qtd before.

Story of the illness:

The issue started about 3 weeks ago, the male clownfish started to get what seemed like a minor bacterial infection. His one eye was popping and a little cloudy. I heard these things can usually resolve themselves so I just left him and kept watch. For the next 2 weeks the popeye would come and go, but he was acting and eating normally, though he also started to get some slime on him and his fins looked a little frayed.

At that point I knew I would probably need to treat with antibiotics but I had some melafix for coral dips and figured I'd give it a try first since he still seemed to be doing pretty well otherwise. I know it doesn't cure them but I thought it would help with his fins healing and I didn't mind adding it to this tank (though I wouldn't add it to my reef).

Well then I started having issues with the female, who was acting and looked fine before. Within an hour of adding the melafix to the tank (very low dose, 40 gal worth) she hid under an overhang and was breathing more quickly. I know melafix can deplete oxygen so I didn't really think anything of it, some people said fish would act like this with it. A few hours later the lights went off and she went back to her normal spot with the male to sleep and she was normal for the day. The next night when I added it the same thing happened though.

First I though maybe the melafix messed with the water quality but it wasn't that. Then I started to think the melafix thing was just a coincidence (still weird though) and that she and the male both might have brook. He had had the body slime and she was breathing rapidly so it seemed like that might be it. But when I read about it people said they will usually die quickly and stop eating if it's brook, so I thought the male just had a bacterial infection since it had been for 3 weeks and no breathing issues.

Just today with the female I noticed that her gills looked damaged, so there's definitely something wrong with her. Again it could be brook or marine velvet, but I'm not sure. I read about both and both supposedly kill the fish very quickly like in a couple days after they show it, but she has already shown the symptoms for a week. So is she already a goner? And which one would she have? She hasn't really been hiding as much the past couple of days but her breathing still isn't right and her gills look pretty gross, like they're frayed, I'm surprised I didn't notice it. She is also still eating well. Can bacterial infections affect the gills or is it definitely a parasite? She does not have any visible slime, color change, dust, or white spots so maybe more likely to be brook but idk? And if it isn't too late what should I treat her with?

Then also what antibiotics should I treat the male with? And I suppose I will have to treat him for whatever disease the female has at the same time, will that be more stressful for them?

I'm not worried about the damsels. They are not showing any symptoms of illness, but even if they did I wouldn't be able to catch them and I wouldn't care as much about them, they're the only fish in the tank otherwise. If the clowns do survive treatment they won't go back in that tank so it shouldn't be a problem.

Sorry for the long story buy can anyone help with the diagnosis and treatment?
 
First off, when was the last time you added something new to the tank? If it's been awhile, I doubt you have Brook or Velvet, as both are fast killers. However, Ich is very possible if you didn't QT.

Bacterial infections can affect any part of the body (including the gills & eyes). It sounds like maybe you haven't done a WC in awhile. Poor water quality doesn't cause infection, but just like when you or I go into a dirty swimming pool with a cut, it can help spread infection. Also, since fish live & breathe in water, poor water quality will compromise their immune system. Doing some WCs will help but if this is a bacterial infection that's getting worse, antibiotics might be required. Lately, Furan-2 has been my weapon of choice. Maracyn 1 & 2 are good too, although expensive IMO. Neither should be used in the presence of corals/inverts, so a QT might be needed. Honestly, getting them into some freshly mixed s/w in a QT might help too. Just make sure temp, pH, SG all match your DT.
 
Thanks, yea 9 months since anything was added to the tank but I thought they could get velvet or brook any time if not qtd like with ich. Just everything I read seemed to say the breathing issues were parasites. I am almost positive whatever it is, it isn't ich. I know what it looks like and usually even if mostly in gills they get some white spots and none of my fish have ever had a single spot. Well it's a bit of a relief if it isn't those since I won't be able to pick up meds until tomorrow, a bacterial infection doesn't seem quite as urgent.

I know the first clown prob got the infection because I hadn't done a water change in quite a while after I had kind of moved on from that tank, plus he gets beat up at times from the female. The water always tests out perfect but I imagine it was still just dirty and would have had a lot of bacteria since it hadn't been changed.

When I noticed him getting the infection I did start doing some water changes but after adding the melafix I didn't change it so earlier today I did a larger one. Maybe it will help.

And I know not to use medications in the main tank, I have a lot of live rock in there and when I finally do take the tank down I want to use it since it's pretty established, wouldn't want to ruin it. I have a 20 gal hospital tank, not cycled but I can take a filter cartridge from the main to help with that and use 50/50 tank water and fresh then I'll start treating.
