White Spot On Danios Mouth?

[tom_os]

no signs on the other fish, just this one and just on the mouth.

i dont have another tank

 

[WILDER]

it's wise to have an issolation tank as its not wise to medicate a whole tank if only one fish is ill.
Anti internal bacteria med by interpet.
Columnaris spots are quite hard to get rid of.

ok well i could get another tank in the next few days but i dont really want to have to spend much money. what should i look for in an isolation tank.

any special requirements?

Issolation tanks really depend on how big the fish you keep.
If you only have little to meduim size fish you can get away with 4 to 5 gal.
You will need a heater, airstone, and filter.
If you can't get the tank just add the bacterial med to the whole tank.
Don't forget to remove black carbon if you use it in your filter.
Increase aeration as med reduce 02 in the water.
Best to have issolation tanks as fish can build resistance up to meds.

ok well its just 1.5 inch fish

i will get some of the med you suggest

is there any chance this could be due to stress because he is getting chased alot and i am still in cycle although right at the end

 

[WILDER]

Yes stress and bad water quality can cause weakened immune system, thins the slime coat, burn there skin and gills, blood dosn't flow well through the blood vessels.
I would do a water change and add the med.
Anti internal bacterial med dosn't kill benefical bacterial in the filter, but it can sometimes knock water stats slightly.

Also fish will pick on ill fish.
Danio are better in bigger groups to cut aggression out, you need a least six.
But I wouldn't add anymore till tanks cycled.
