Black Mollies dying

I read they can live between 2-5 years estimated. Anyone here have them? How long did they live and did you have them in brackish water? (I had some years ago, but my cat kept getting the lid off the tank and every morning I found him hanging on with his bottom in the tank-they didn't last long after that)

I think we have had ours a year. I wrote in about my Black Skirts fins, added fish ,medicated and so on. Everything has been fine. So, the Mollies recently had white on them and I treated the whole tank. The rest of the fish are fine, but the mollies are always at the top and one is breathing very hard, and lost a lot of weight. So my high PH level was the only one out of range,like 8.3 or so. I do weekly water changes etc. The rest of the test were fine. Oh, I have gotten a new heater and temp sticker.

I'm not asking for a help on whats wrong, but if their age has anything to do with them being ill and not the others. The 8 misc tetras and 4 Glofish are acting and look fine.:-? (29 gallon)

Hi! I owned mollies. I found that dalmation and black mollies (regular and balloon mollies) tended to have so much more problems, however I have no idea if that is related. However, mine lasted about a year.. take in mind you usually buy them as adults so they'd have been 2-2.5 years old at least. They should be in brackish water, however people fail to realize one teaspoon per water change makes the water more salt wate than brackish... if taking out 25% put in 25% of salt you usually put in :)

Also, they tend to be very very prone to cotton mouth. Even if it does not show up on their mouth, it will show on their body and fins as a strange white spot that refuses to budge with mild treatment. Best case is Maracyn and Maracyn 2 combined to battle it. Trust me! I've gotten 3 mollies with it, first one was orange (Mama) and she died since I thought it was regular fungus, and treated it so. Second was a dalmation black molly female who had it and was having troubles with birth. Third was her baby, who first showed signs on his mouth.

Thank, Im sorry I asked you to reply :). One molly had the white near its mouth/gill, and the one with the "smushed head" had it in the middle of its body. Those were gone within two days of medication. Yes, I feel worse they are not in brackish water.

The glowfish that died- the right eye out, and gill closed, just odd. Didn't look like fungas, maybe a reaction to the meds? The belly is round but I know they can bloat when they die right? The high ph is down to 8.1/8.2 and I did just did a water change,thinking maybe it would help. Thanks you :)

Oh, it was two days ago for the other water change, not yesterday.....

When a fish dies always do a water change. Mollies actually live well in non-brackish water, I had half of mine (the aggressors split up) in non-brackish water with the platy fry, and the tehrs were in brackish water and they still lived about the same... however the ones without salt did get the cotton mouth. It is highly contagious, so you'll need to treat the entire tank and any live plants you want to quarantine.

And it's fine :) I know a bit about mollies so I can help

I lost another glofish this afternoon, and my purple one is breathing hard at the top. Got the dead fish out, 25%(estimated) water change and I have just put in the Tetra Parasite Meds,thinking maybe this is it? There is no fungus on any of the fish, temp is fine. I checked the water again and this is what I have...

Ammonia:25 maybe a little less. api test,,yellow is always off...
Nitrite:0
Nitrate:10-ppm
pH:7.6+
highph 8.0-
