Hi,

About two weeks ago I got ten rummynose tetras for my 120 litre tank. After a couple of days I noticed that one had a few white spots and decided that the next morning I'd get some medicine to treat it, since it was quite late at night by this time. The next morning it seemed as if more of the rummynoses had some white spots but not many at all, so I assumed that it was in its early stages. I got Waterlife Protozin, which can be used to treat whitespot as well as some other infections. Unfortunately, despite having done a water change before adding the medicine and turning the temperature up a bit, all but one rummynose died. I am sure that this last rummynose will be fine because he looks perfectly healthy and he never seems to have had whitespot, even though all the other rummynoses did. I'd just like to ask a few questions about restocking.
Firstly, I'm planning on getting him some more tankmates on thursday, at the end of the second dose of medicine. I'm guessing all the whitespot parasites will be gone by then seeing as the medicine should have killed them, and if not, they wouldn't be able to survive without a host. Is this correct, and do you think it would be ok to get some more rummynoses on thursday, if the last fish that died from whitespot passed away on Sunday? I don't really want to be leaving the remaining rummy on his own for too long as I know that they are meant to be shoaling fish.
Also, would you consider the shop I purchased the rummies from to be to blame? For example if the rummynoses had whitespot in the shop but it showed up a couple of days later in my tank because I've heard the white spots can take a while to become visible after the parasite has actually attached itself to the fish. Or is it more likely that the fish got whitespot because they got stressed about getting moved around and being in a new environment? If it is possible that they got it whilst in the shop then I'm less inclined to go back there and maybe see if there's another place nearby that has rummynoses in stock. If I did go somewhere else, and didn't get the exact same type of rummynose as what the remaining fish is (as I know there are a few different types of rummynoses), would they all still shoal together?
What do people think about travelling a bit further afield to get fish? Would a twenty minute journey be any better for the fish than an hour and a half journey? Or would the latter be totally fine? I'm just thinking about the temperature drop really. I know rummynoses are meant to be pretty sensitive.
Also, since there's been only one fish in the tank for a couple of days now, I'm guessing most of the bacteria that convert ammonia to nitrite will die by the time I get some new fish, so should I only add a few at first, then a few days later add some more, or would it be ok to add seven straight away?

Sorry for this long post, I just have quite a lot of questions to ask about it! Thanks to anyone who reads it or replies.
 
It seems a bit drastic for all those fish to die from white spot in such a short period of time. Did you calculate the correct dose of treatment for your size tank. Also when using a medication and also turning the temperature up there is less disolved oxygen in the water so extra air ation is needed. An airsone for instance.

I would almost definetely say that the fish had white spot before you ourchased them. Probably the stress of being purchased made it flourish. I personally dont go back to a fish store if they show signs of disease once i get them home.
 
Thanks for your reply. I was surprised that so many fish died. Especially considering that I heard there was an excellent chance of completely treating white spot if you started treating it early enough, and we definitely caught it in the early stages when not many fish had very few white spots. We definitely worked out the dosage correctly. 8 mls needed for a 120 litre tank and it was easy to measure out with the cap. To be honest the medicine just didn't seem to work at all. The white spot just got worse and worse which I wouldn't have expected to happen. Thanks for the info about the airstone, I didn't actually know about that.
Yep, think maybe I'll try a different shop.
Anyone else got any advice?
