Fin Rot?

[Singenkatzen]

I have question about this...

I had a male guppy that started acting funny last week (floated near my filter, would get stuck to internal filter, looked a little bloated [fed him peas and was not bloated the next day]) but was still eating. On monday night I noticed that he was keeping all his fins closed and one of his side fins was split. I had to wait until wednesday to buy medicine because that was payday. I bought Trisulfa. I put the medicine in the tank wednesday and thursday morning, but when I came home last night he was dead. I am continuing to do the treatment because it said to do it for five days even though he died, because I am not sure if he could have passed it on to my other fish, could it??? One of my female swordtails is now keeping to herself, staying near the bottom and holding her fins close as well. No one else seems to be affected-- all are eating and moving throughout the tank.

Levels: Ammonia >.25
Nitrite 0
Nitrate 0
Ph 8.0

Should I do the last two days of treatment, stop or try something else?:help:

Do the full treatment. Always do the full treatment of any any antibiotic (for your fish or yourself). Even if the symptoms disappear.

How long has the tank been running? based on the tests you posted it looks like the tank hasn't cycled at all. Ideally the Ammonia should be 0, Nitrite should be 0, and Nitrate should be >0. Your pH is little high (don't worry about that yet).

If it's the 5g bow that is in your profile then it's got way too many fish in it for it's size. I don't mean to scare you or anything, but those fish will die unless you remove them. If you can I would recommend returning the swordtails if you can. They are great fish but they get way too big for a 5g. I wouldn't put any more than 3 or 4 guppies in there either, but keep in mind in an established tank the guppies will breed like rabbits if you've got males and females together.

Here are 2 articles you should take a look at.

Looks like your water is the source of your problem. Fin rot is usually brought on by bad water quality. You are not cycled, so definitely read the sticky and pay close attention to the 'fish cycling' portion. If you haven't already start doing water changes immediately. It's the best cure for fin rot.
