Black Mollies Have Strange White Spots On Their Heads And Bellies

[PA_fishlover]

I have a 10g tank with some black molly fry in it. Most of the fry seem to have a silvery/whitish color on their bellies. This has been there for quite a while (weeks now). I just got done treating the tank for ich and that has seemed to clear up. Now I've noticed that some of the fry are developing a white spot on the top of their heads. It does not look like ich. It looks like they are wearing a little hat. The larger fry that I was just about to move to my main tank now has the spot on his head as well as his belly.

Any idea what it could be?

I need to move some of these fish out of this tank because it is very overcrowded, but every time I'm just about ready to move them, I find something on them. It's really frustrating. I can not get the tank clean any more because the little things are like poop factories. I gravel vac the tank twice a week and I could clean it every day and not get rid of all the crap.

I think tomorrow or the next day I'm going to drain the tank and thoroughly clean the gravel.

Any suggestions or ideas as to what the white spots are?

Mollies do better in brackish water.
Can you post stats in ammonia,nitrite,nitrate,and ph.
The spots do they have a circling of red around the eges, or a spot in the centre.
Anything sticking out of the spot.

Tank stats:

Ammonia: 0
Nitrite: 0
Nitrate: 10
pH: 7.8


The spots have absolutely no red. Just a silver/white spot. Flat, not raised or any texture. The bellies have a silver color to them instead of black like the rest of the fish.

I know they need salt. I have cories in the same tank, so I can't add a ton of salt, but there is some in the tank.

I had thought of columnaris, but it does not have any redness surrounding it at all.

Do the have a greyish slime on them.
Any signs of flicking and rubbing.

They are not hat shaped. They just make it look like they are wearing a little white hat. The spots are totally flat. Not raised at all.

It's only on a few of them on their heads, but about half of them have the silver bellies. The largest fry that is 3 months old has not had a white/silver spot or color to him at all until today. He's been totally black until now.

To be honest I would try a bacterial med on the fish, as darkening in colour can be a sign of a bacterial infecttion.
Black patches can be ammonia burns that are healing.
Has the belly swollen up.

Can you load a pic up of the fish.

 

[PA_fishlover]

He's supposed to be all black. There has never been any darkening. There are not black spots. They are silver/white areas.

 

[WILDER]

Sorry not with it at all today read it wrong sorry.
If there no signs of flicking and rubbing or laboured breathing, I would go the bacterial route for now.
It's not always easy as bacterial and parsites can show the same symtoms.

 

[PA_fishlover]

It isn't the best picture, but the black fish in the middle has a white line on the top of it's head.
