I bought three balloon mollies and added them to my fish tank with the other fish. Within four hours the mollies have white stuff all over their bodies? It does not look like the ick to me. Not sure what to do? :(

My fish has skin problems but whatever that I used to treat it didn't work. Two days ago I found a white node on its lower back. This morning it left an opened wound. Can I submit a picture tonight before a quicker and more accurate diagnosis ? Where do I submit to if I can? Thanks.

    Sounds like a fungus or ich.  If you scroll up in this Animal World article you can determine (via symptoms) what you fish has and then provide the recommended treatment.

Me and my mum and dad had gone out for the evening and when I arrived home I checked my fish tank to find my red tail black shark at the bottom of the tank basically bent so his nose was touching his fin and he was covered in white patches. also he has internal bleeding next to his front lower fins just really worried that my other fish may catch what ever he had. He has been acting odd for the last two weeks loss of appetite and hiding away in a rock by himself really need some advice because I'm worried that I might loose the lot again which I don't want to happen again after my heater stuck on and raised the temperature to 42 degrees killling all my fish please help urgently!

I have an African Clawed Water frog about dix years old. About a week ago I noticed she had a white slimy substance that appeared to be attached to her foot, she lost her appetite, and hasn't been using her back legs. I treated the water with Tetra's Life Guard and purchased a bubbler to ensure proper oxygen. I had recently been fighting some algea, but not anything out of the ordinary. What would explain the possible paralysis?

    Frogs will create a slim coat when stressed.  Sometimes water conditions others in tank stressing them out?

    Seperate fish and get antibiotics in the tank to treat for parasites of bacteria.

    Was the tank cycled? Could be too much amonia.

I have read through all the diseases and still cannot figure out what the disease is in my tank.
I have hard water that is softened by a water softner,
have a 55 gallon tank with sand,
mostly real plants and just a few plastic (the plants are growing fine)
tropical fish (plecos, catfish, glass fish, neons, koli loaches, zebras)
have snails which is under control
filter is aqua clear 70
on the dip test strips the nitrate 40 ppm is good, the below .5 ppm is good, it shows i have soft water, the alkalinity is high and the ph is high. After talking to the pet store they said the last two are just fine
I tried to lower the ph and alkalinity with the meds to lower but it was killing my plants and was not making any difference on the dip tests. The only thing I could find to lower it was using distilled water to fix it but was told not to by the petstore.
I can tell who the next fish to die is. This only happends one fish at a time. They act normally, but inbetween the nares I can see a peach colored mass (?) inside. Last night my last hatchet fish died. I predicted the day before this was gonna happen. I could see this peachy color in its nose and its eyes started turning red, they bugged out a little but this does not normally happen. After it dies its eyes do not cloud over.
Within a few days to a week the next fish will die or show signs of the same thing.
Any suggestions?

Hey, I got a bamboo shark and today when I did a water change it started acting strange swimming in loops and I have to sit by the tank because it lands on its back. I'm hoping it's just something that will go away cus Bruce was just fine till I did the water change.

    Usually something like that is because of stress or the conditions of the tank. Check the water, temperature PH etc and make sure all is OK. Attached is Animal World Article which summarizes various diseases but also behavior things. Scroll down and look up symptoms and recommended treatment is there. OK?

    Well sad to say it died and my blue tang died and a camel shrimp died as well it was because I got a fish that was ill and had tb and fin rott and ich and I went by the instructions on the bottle and on the second day of treatment is when all hell broke out it was that nox ich treatment but my cc seastar, clown fish, damsel, snowflake eel, big camel shrimp, hermit crabs, sally light foot, all seem to be doing well. I'm just glad I didn't lose all my fish. P.s. if you get a fish that has a sunk in stomach and won't compete for food get it out it has tb which can wipe out an aquarium in days.
