tailrot

my tank is going on 2 months old now. i have had fish die from pretty much the beginning. they all start losing their tail. i have a few platies in their that have made it from the beginning with no problem. i added 2 swordtails yesterday and the male is already starting to get white right on the tip of the tail. samething happened to the last male swordtail.
tank has lots of plants and water always test fine when i carry it to lfs.

Have you only had the platys and swordtails?

Possible Pictures?

If it keeps happening then your water is contaminated possibly.

How often do you do water changes? When was the last one?

What are the water parameters if you don't mind posting? If you don't have your own test kit I would recommend API Master Test Kit.

Also, what kind of plants do you have in there?

Are your fish Flashing? Do they have clamped fins?

Under the Tropical Fish Diesase under Important links there is this page with this information. I think this is what your fish have:

Bacterial Fin Rot
Symptoms:
The fins are frayed and getting shorter. Edges are whitish.

Causes:
Overpopulation, severe stress especially on transit, untreated injuries, poor water quality and poor maintenance are the main causes of fin rot. Fin rot can occur in connection with columnaris, fungal overgrowths, lesions and as a secondary infection to parasite infestations. Ffish begins to have difficulty swimming due to the damaged fins.

Treatment:
Broad spectrum antibiotics, frequent water changes are a must to improve water quality

This is another possibility but the Bacterial Fin Rot is more likely because of your description

Osmotic Shock
Symptoms:
Detachment of mucous membrane, fins appear to have been blown off, internal diseases become the consequences, increased vulnerability to skin diseases, gill and fin rot.

Causes:
When fish is transferred from water with high conductivity (high salt content) to water with low conductivity without an intermediate phase for adaptation, they suffer from osmotic shock. The fine cartilage joints in the fin rays can burst due to the high osmotic pressure. The fins fall off in large pieces and the fins are eventually infected with fungus and other bacterial infections especially when the fish becomes extremely weakened.

Treatment:
This is more of a case of prevention rather than actual treatment. Measure the conductivity between the water where the fish is and the water where it is to be transferred. The addition of mineral salt to the one with higher conductivity level will help minimize the chances of osmotic shock. Give the fish time to recover from the upheaval. Then, proceed to lowering the conductivity level to the desired level by doing small water changes over several hours.

I am assuming your tank is cycled because its been running for 2 months correct? Did you originally put fish in there after it was cycled or before?

I would say water change is going to be your best bet, although it might not completely solve the problem. If you don't have any fish in the tank right now....you have a few options.

You can do a massive 75+% water change.
Clean your substrate and everything to optimize the changes of getting the bacteria out. maybe even rinse your filter too...(in aquarium water)

After you clean it I would check all parameters.

I am hoping one of the more experienced members can come on here to help. I haven't had too much experience with fin rot, especially not at such a scale.

My betta died of Bacterial fin rot about a week ago, he was in a community tank, I removed him to a hospital tank and changed the water before any of my other fish got it. He didn't make it. The other fish started flashing so I raised the temp to around 80-82 and did another water change the next day.

I did water changes every day for about 3-4 days after that until I felt safe. All the other fish are fine now though.

yes, i do have fish in there now. most of the time it is a new addition that dies. i did start the tank with fish, which i was told that would be ok from petco. i have an api master test kit ordered.

what does flashing mean?

The fact that you have fish in there that are NOT being affected and its the new fish that it is happening to it there are a few possibilities.

1) the fish store COULD (not sure but could be) giving you bad fish...a lot of people quarantine their fish for a week before putting them into the community. Return the dead fish if you can (I think they have a 14 day return period).

2) Your water could be contamintated and the fish already in there have built up immunity or extra defense?

3) The tank is contaminated and the fish you bring home are stressed and therefore weakened and will be more vulnerable to this bacteria.

I would guess its one of those.

I was told the same by PetSmart. As we have both found out that is not the way to do it.

Flashing is when you see your fish doing drastic movements against a sharp object. Looks like they are trying to scratch themselves...or something underneath the skin. This usually means they are sick. Usually fish with bacterial infections will flash. That is a warning sign of the infection. If they are flashing then they are already infected even though you might not have physical proff yet.

API Master test kit works great.

I would try cleaning your substrate well to get rid of all the extra bacteria and the water changes.
