Mass Death Of Guppies

[ronkey]

hi
i have a 10 gallon tank, at the weekend I changed the fish in the tank which where six gold tetras which had been in the tank for four months. The previous week my daughter went to our local tropical fish shop and they had four tanks full of new fish which where guppies we decided to exchange the tetras for the six gupppies which we bought on saturday all fish where perfectly fine they where swimming around together and was eating the food we gave them. on sunday we where out for most of the day towards the end of the night i noticed that a couple of the fish where on the bottom of the tank the tails had gone like string the yellow guppies went first all dying one after the other which was through last night and all through today there is one orange guppy left which seems to be fine at the moment.
can any one tell me what type of illness causes their the fan tails to go like string.
The tank has 10 percent water changes weekly and the freshwater testing kit shows there are not any high levels harmfull subtances

Bacterial finrot which guppys are prone to.
Need stats in ammonia,nitrite,nitrate,and ph.
Tail and fin rot can be prevented by keeping ammonia and nitrite levels low, adding salt at regular intervals, and quarantine of new fish. Guppies are particularly susceptible to this disease, and you will first recognize it as a ragged edge on the tail fin. Healthy adult tail fins should have a fairly straight edge, though sometimes adolescents will have temporary ragged fins due to uneven growth. As the disease progresses, the other fins become ragged, and the fins develop a white (sometimes though not always, fuzzy) margin. Sometimes, the fins will also develop red bloodspots. If the disease is allowed to continue, your guppies will die. In most species of fish this disease is a combination of bacteria and fungus on the fins themselves, however guppies tend towards acquiring an internal bacterial infection which spreads to the fins. You may try the salt treatment, as this sometimes does the trick. If that doesn't work, an antibiotic such as tetracycline can be used. Let your pet shop help you. They will specifically need to know if you use a bio-filter as many antibiotics will kill your filter.



You will need a med called myxazin by waterlife.
The guppys that are left how much of there fins have gone.

There is only one left at the moment it seems to have kept its colour and the fins have not gone ragged yet ,it also is still quite lively the test was done last week can not remember the exact levels but knew that it was okay will be testing again tommorow for exact resualts

Ok, get them test results done fast.
If there only one guppy left in the tank add some salt even if it household salt.
One tablespoon to 5 gals, but add it gradually rather than in one big dose.

thank you for your advice if this fish survives and does not develop this fin condtion is there anything i can put in the tank to prevent new fish from devloping this dieses when should new fish be added or is it worth considering a more hardy fish

 

[WILDER]

The best advice I can offer is to quarantine new fish to stop desease going into the main tank.
I started off with guppys and only manage to keep a few till 7 months old.
There not a hardy fish anymore prone to alot of deseases, and the lfs guppys are usually on there last legs when buying them.
If you want to carry on keeping guppys the best thing to do is find a good local breeder of them.
Been where you have with guppys them dying all the time and couldn't cope with it so stopped buying them
I have harlequins, black neons, x rays tetra's, glow light tetra's, seem to be hardy fish.
