Possible Disease......

[Robbo99999]

I have a shoal of Danios as part of my community aquarium.

I introduced a couple of new plants this weekend, with a couple of snail hitch hikers. Since this, one of the Danios has developed a white blister on his lower jaw, front centre. Pretty sure its not white spot as it is localised the the mouth, the fish has no further symptums.

Any ideas what this could be and any possible treatments? I know your supposed to remove infected fish, but I have no back up tank and would rather not kill the fish.

This can be rather serious if it is diagnosed as mouth fungus... a cottany white fluff eventually appears around the lip area which gradually eats away at the lips and mouth, and also infects other fish..... The fish has to be removed to a different container and treated with a salt solution (a heaped teaspoon of salt every 2 hours per gallon of water for 6 hours)....

If any improvement is noticed during the next day or 2, you need to add more fresh water and continue periodic water changes until all the water is back to the original solution before the fish is placed back in the community.... ( very likely that it can be fatal).....(I'm not sure what causes the diseas).....

So have another look & see if there is a cottany appearance to this infection.
