Here We Go Again...black Spots, Weird Behaviour

[Leeore]

Tank size: 10 gallon

Ammonia: 0ppm
NitrIte: 0ppm
NitrAte: 20 ppm
PH: 7.6 ppm

New addition to tank: Small bushynose pleco
Fish in tank: pleco, 2 mollies, 2 swordtails



Roughly a month and a half ago I had to treat my tank for Callumanus worms. I treated with Levamisole and it worked great. Unfortunatly, I lost my male black sailfin molly during treatment for some odd reason. He became very very bloated, listless, and his eyes bulged out so bad it looked like they were going to pop. At the time my water specs were about the same as above. After treatment all seemed well, but then a female dalmation molly started to become listless with laboured breathing. She died shortly after. I still don't know what caused this. Not too long ago I gave my remaining fish (Mentioned above) medicated fish food to help with possible bacterial infections from the worms. Everything seemed back on track, so I added a pleco. Now, my 2 mollies are acting like the dalmation that passed away. Laboured breathing, listlessness, clamped fins. They become excited when I approach the tank to feed them - they eat well. But go back to acting strange. Upon staring at them, I noticed some flashing with the one molly - along with lots of tiny black spots on her (About the size of a grain of salt). The one sailfin also appears to have some of these spots. I cannot tell if it's on the other molly because she is mainly black in color. The tank is well airated.

Any idea what this could be?

What test kit are you using.

have the fish been kept with snails.

Did you buy the new fish from the same lfs.


Black Spot

Symptoms:

Your fish will have small black spots measuring about 2 millimeters in diameter. These can be found anywhere on the fish�s body and fins. Cysts may be found in the internal organs. It is typical for African Cichlids, however, to constantly have little black spots, especially around their mouths. These black spots should not be mistaken for "Black Spot." These are scabs, which have resulted from digging in the gravel or from fighting.


Cause:

Larvae of parasitic digenetic flukes, Cercaria and Metacercaria. The spots seen contain larval stages of digenetic flukes. The life cycle of these parasitic flukes begins when fish-eating birds and other animals ingest fish infected with the parasites. Once ingested the parasites mature in the intestines of the host animal where they produce eggs. The eggs are then deposited into the water where they hatch and infect the livers of aquatic snails. The parasites then develop into a second and then third larval stage before leaving the snail to seek out a fish host. This type of parasitic infestation is most common in wild caught fish and pond fish.


Treatment:

Remove all snails from the aquarium or pond to end the cycle of infection. Treatment is rarely necessary and can be difficult if not impossible. Minor infestations may clear without treatment as the larvae will eventually die and be absorbed by the host's immune responses. Copper Sulfate may be helpful in severe cases.

API Freshwater master test kit

No snails. They did not appear to be with snails in the lfs.

And yes I bought the new fish from the same lfs


I was thinking maybe black ich?


EDIT: my orange mollies eyes appear to be a little swollen, and I noticed a black speck in her left eye.

The only black spots I know of is black spot.
