Black Lyre Tail Mollies With White Fungus?

[who-izzet]

I've got a 5ft tank with lots of livebearers in. All the other fish seem fine but for the only 2 black lyre tail mollies I have. They seem to get the odd patch of a white-ish fungus on them. The male is normally the worse and gets it around his mouth. I've used meth blue over a couple of days in a treatment tank and it normally clears it but within a few days of being back in the tank, it's back on the fish.

I've checked all the water parameters and all are quality. Can anyone tell of any reasons? I have sunset mollies, silver balloons, golden high fins and silver mollies that have no problems at all.

I will point out though that I had 1 blue ram that had a swollen eye about a week ago but with treatment, that cleared up.

Columnaris
Uk myxazin by waterlife and pimafix.
United states maracyn one and two.

Thanks for that. The water quality I have is good but I had a fairly big rise in Ph about a month ago which could have been the cause?

I will see if I can get hold of Primafix.. I guess I have to treat the whole tank with this? I think it's 400ltrs.

ok Pimafix ordered!

 

[WILDER]

Yes stress due to the ph being unstable can soon fetch on columnaris.
You will also need myxazin by waterlife with the pimafix, as uk meds are not that strong for columnaris so need to use both.
Good luck.

Thanks, I better start looking for the myxazin then. Can both of these be used exactly at the same time?

 

[WILDER]

Yes.
You must increase aeration in the tank as meds reduce 02 in the water.
Remove black carbon from the filter if you use it.

 

[who-izzet]

Yes I'll remove the carbon from the filters. I can add another air pump, I have pleny of spares. I've just ordered the myxazin now so hopefully I will have them in a couple of days and the melafix will keep it at bay.

These black mollies have 2 week old babies in another tank, not showing any signs of anything. Would a small dose be ok in their tank just to be safe?

The help is much appreciated thankyou!

Turn temp down by two degrees for now as colunmaris thrives in warmer temps.
Just water changes to the tank should be ok.
Columnaris live in tank water it only takes a stressed weakened fish for columnaris to break out.

Ok thanks for the help. I will lower the temperature slightly. I do a 5-10% water change every week.

 

[WILDER]

Water changes lowers the bad bacteria in the tank.
Good luck.
Keep nets and equipment steralised that how desease pass from tank to tank.

 

[who-izzet]

I keep the nets steralised so I'm ok there. The babies look very healthy so I doubt there is any problem in the tank. I've put them in a tank with meth blue last night and the fungus seems to have cleared a little on the female again. The temperature has been dropped to 25C in the main tank.

Is it likely I will get a break-out on my swordtails, guppies and platyies while I wait for my medication to turn up? I think I had something like this about 3 years ago that wiped out about 10 livebearers but the tank has been brilliant ever since.

 

[WILDER]

I can't say to be honest it depends on the columnaris strain some strains are nasty an can wipe a fish out in hours.
Water changes till the med comes.
Good luck.

 

[who-izzet]

I've done water changes, checked the water quality again, turned down temperature.

It's not looking too good at the moment. The mollies have got slightly worse now. I've noticed 1 platy starting to show symptoms and sort of hovering in the water letting the others bite it and it also has a small white patch on it's lip. Let's hope the medication turns up tomorrow! Its a big tank to treat though!

I'm guessing it won't really effect the bigger fish like Kissing G's etc?

Would it be an idea to move all the livebearers into a smaller tank and treat them there? I have a spare tank already set up.

 

[WILDER]

Sounds lke a bad strain hope the med arrives tomorrow.
Good luck.

No meds yet but 1 more platy now infected with small patch under bottom fin and my huge silver molly now has pop eye! Hell this one is going through the tank! I think the treatment will be here tomorrow but will it be too late.

On a good note a platy had babies and they are all ok. I have removed them into another tank.

Do you think I should move all the livebearers into a small tank as it seems it's just them effected and treat the tank? Would the fresher water help?
