My fish has suddenly swelled up?

Last night whilst cleaning out my fish one of them, Platinum, jumped out his bowl. I returned him and checked him over, i noticed that he had redness around his gills and tail. I looked this up and thought he had mild aciodosis. I had already started to change the water so i changed it (i dont use tap water) and put them both back it. The other fish Diamond looked fine. Just now i went and looked at them and both (Diamond) in particular has suddenly swelled up. They are normally long and thin and now are fat and stubby!!! What has caused this and how can I treat them? Please help as I am so worried, I have had Diamond for over a year and I adore him.

Update:

Dropsy-I did intitially think that this was the problem however they dont have the caractersistic "pine cone" effect

Update 2:

Just checked the Ph level and it is 7 so neutral.

Update 3:

However, they are both doing the hyperactive scitzy thing that is indicative of acid poisoning?

Update 4:

It is a non-traditional bowl, i removed them because I was told to do that as they get stressed by water changing. The water used is Malvern water (eg pure water i literally get it off the hills spring as our water is very nitrate rich). Again advised to do this by a fish breeder in the area. The tank has no filter but it is not neccassary for hardy fish like the type I have. I am actually currently setting up there new tank with a filter (a big proper aqaurium) but the water needs to stabalise. The ammonia level is fine i checked it

    Jumped out of his "bowl?" "Cleaning out?"

    You DO have a fish tank, not a bowl right?

    With proper filtration, heat, air???

    You NEVER EVER EVER tear down and "clean" a fish tank.

    Keep the filters clean, do partial water changes. That is IT!

    If you really do have a "bowl" and clean it, the water quality is most likely pretty poor and fluctuates more than fish can adjust to.

    "Swelled up" if this is internal it could be just about anything. From gas, over eating, to parasites, to infection.

    Being hyper active could also be a sign of really poor water quality. High amonia happens in tanks (or bowls) that were never properly cycled. Amonia poisoning's first symptom is rapid breathing and darting about. The fish's gills are litterally burning!

    Without more information, not much else I can say. Small water changes are always good though.

    Never the whole thing, just 10-25%.

    As for how to treat, you have to first have a pretty good guess as to what is wrong. Not enough here to tell you that. Sorry. My best guess is their water is toxic.

    Read up on aquarium cycling and see if you missed something in the set up.

    Probably swim bladder disorder if your fish is just swollen and bloated, however the red bumps could be a sign of internal parasites. Be careful treating with those hardcore chemicals out there. There's special food to treat internal parasites, so my suggestion would be to start with just the food for now, seriously decrease how often you feed your fish (that should help out the bloating), add some aquarium salt (even if freshwater fish- 1 Tbsp. per 5 gallons), if doesn't get better within a couple of days or you start to see little worm like things coming out of your fish, do some research on what kind of chemicals to use. Maracide is a good choice, but there are other options too- it's a matter of personal preference and your comfort level using the chemicals, because the harsher the chemicals the more risk of serious injury to your fish. Hope that helps somewhat.

    I`m thinking it`s swimbladder or dropsy. These are both difficult to treat and if not caught immediately, the fish will usually die. I have treated a few of my fish with Maracide and I always remove them from the tank. KanapPex and Maracyn 2 are also good treatment medications for dropsy.

    Hi im katie...

    My cousin had the same problem, he had 2 fish (don't know their names) and they were swelling up too and sadly they died.

    He never cleaned the fish bowl properly and it was his fault really because he never hardly looked after them... poor things

    It could be that or it could be that there is too much sunlight on the bowl so keep Diamond and the other fish away from sunlight.

    It is a disease... I am so sorry about your fish. I love fishes too.

    They wont last long and I am not trying to upset you if your so emotional about them.

    Please don't be upset at least they would be in a better place. :-/

    How do their scales look? If they are flipped up making the fish look like a pine cone than it could be that your fish have dropsy. Dropsy is bacterial infection.

    Maybe a chemical on the table got onto the fish, and into the water.
