Help! Fish Dying!

Thanks for viewing, please help me anyone. I have a 10 month old fighterfish, have had him for about 6-7 months. He is in an 86 litre, not sure in gallons, like 28 or something i think. Water parameters are all fine and stable, and all of a sudden when i got home from a 4 day holiday, hes lying on the bottom of the tank dead. I reach down with my net to get him out and woosh, he swims off. He has been doing this non stop for about a week. Then i spotted, just above his gill, on his head, he has a white patch, the size of a pin head, which is white, and flat but then it has like spike looking things coming out, and it looks kinda cottony. He has also lost both anal fins, and its all fluffy and stuff down there. I have seperated him into a little cut open coke bottle with tonic (a general fish disease medicine) and salt, and i put a little plant in there to aerate it. Is he going to die, do i have to put him out of his misery, i REALLLLLLY dont want to do that. But it saddens me every time i come home to see him just lying there so sick. WHAT DO I DOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO!?!?!?!?!

Here are some photos. Ps the water is blue because the medicine i gave him makes the water blue.

Oh dear, that looks horrible That's going to need more than a tonic. Which country are you in? Might just be the pictures, but in the top one, are his scales sticking out a bit too?
The plant won't really help, he's going to need very regular water changes. Was he alone in the larger tank?

As said above, in the first pic his scales seem to be sticking out. In this case, it may well be dropsy. In general, once thats taken hold its too late.

Im sory, I know how hard it is. I had a ill female fighter lately, no matter what I done I couldnt get her to full health again, so I made the decision to end it for her. Very hard decision to make. Hope he comes through for you though

bet you havent got a filter in there, he needs a bigger tank with a filter and proper treatment with fungal medication and salt, meanwhile small daily water changes will help. di

looks bacterial to me. i see no signs of dropsy. needs antibiotics and clean water+good food. are other fish showing any similar symptoms? what med are you using now? (meth boue or copper sulfate? i assume one or the other as your water is blue). while those are good for fungal disorders and certain parasites, will not really help a bacterial infection (i suspect columnaris). have a look for good broad spectrum antibiotic. in the meantime, keep his water clean with frequent water changes. hopefully the antibiotics will sort it out. make sure none of the other fish show symptoms as columnaris spreads FAST and can wipe out a whole tank.
best of luck with him
cheers

Hi all, he died a few days ago . I didnt know what to do. no the other fish are fine, he was in with 4 angels and 1 blue gourami. No the plant was just to give him oxygen. Im living in Auckland, NZ, where the fish stores here are pathetic. Hes in a better place now.


RIP Boss

Sorry for your loss Sometimes there's just not much you can do. Don't let it put you off getting another one, although if you do get another one, angels and gouramis are not the best tank mates.
