3 of my goldfish are really sick. i will list the names of each fish and describe whats wrong with them.

Brighton:
Brighton is a fantail goldfish, he is almost a year old *all of them are* He has weird white lumps on him that look similar to this: http://img380.imageshack.us/img380/.....img0005vk1.jpg And half of his body has the scales "raised" but not fully, a few days ago both sides were raised but one has gone completley down and the other one is almost down but still a little raised. And he looks like an akward 8 body shape, it comes out near his rump then sinks in a little at his belly and then comes out again behind his head, hes normally really fat but now he looks really awkward, the last few days he's been eating food with no problem and he still is, but now hes starting to act sluggish. The white lumps come and go and every time they go they come back, at first it was just one and now its two. I turned the temp up to 80, online it says itll help kill the specs but im not sure cause no one seems to know what they are. I want to take my fish to a vet but no vets within all of my county do fish, not even the ones at petsmart ; ~;...

Thunder:
Thunder is a comet goldfish, he is also almost a year old and he is still a pretty small fish. He also had the same white lumps and they fell off today, now he has stomach ulcers * i think because he has big red spots over where his belly would be and they are very swollen* and his slime coat is starting to shed *if thats possible* he still eats but now he too is starting to act groggy and his belly is starting to get a little swollen too, like normally hes very thin and "flat" i would say but now hes sort of round.

Sail:
Sail is an Oranda goldfish, she is pretty well, not much sickness here, but she has these 3 white lumps, and they are huge, one by her mouth that slowly gets bigger and then two right above her head, they dont look like theyre bothering her but they get big and then they get small and then big.

Guys, if i cant help my fish, i cant even take them to the vet, then do you think it might be best to put them down? Are any of these contagious, im scared and i really need some help. My boyfriend and i did a 100% water change on sunday because we tried doing smaller water changes and the fish kept getting sick so we though it was nessicary to do the 100% change. Then they got better,but it seemed like Brighton was getting dropsy so our friend gave us some medicine to help him and we used it and he looked like he was getting better *cause like i said his scales went down tremendously* And now im just scared cause hes getting groggy and so is thunder and i dont want any more of my fish to get sick, guys what do i do ; ~;????
