Swollen Gills
Mollies may have swollen gills if they have difficulty getting oxygen or breathing heavily. If this condition persists, they will die.
Change in Coloration
If your Mollies lose colors, the cause may lie in unclean water. Molly fish which live in an overpopulated tank can be more likely to fade their usual color.
Fins Falling Off
If you notice your mollies’ fins are falling off, you need to take care of them as soon as possible as they may be dying.
It can be due to stress caused by environmental changes. But sometimes, their fins will fall off without reason.
Crash at the Bottom of Your Tank
Healthy mollies do not swim near the bottom in most cases. But if your fish are showing this sign, they may be struggling with health issues.
Bladder problems cause them to sink to the bottom of the tank due to their inability to control their buoyancy.
Mollies with bladder problems also have difficulty staying upright and eating.
White Specks Appear on Fin Skin
White specks might be a sign of protozoan infection
It might be a symptom of protozoan infection. Protozoa in mollies may come as one result of poor water conditions.
Sickly Odor
A sickly odor from your aquarium can also indicate that your mollies are dying.
This odor shows that bacteria are growing inside your tank while your fish can’t survive anymore.
Moreover, mollies need the proper amount of oxygen to live, while too much ammonia from other fish will make your mollies sick.
Lethargy
Lethargy is one of the other symptoms that your mollies are dying from illness or old age.
The most obvious sign is that your fish seem lazy for a long time and don’t move around often.
Loss of Appetite
Mollies will stop eating if they are dying or sick. So eating less or not preferring food may tell if they’re fighting illness for an extended period.
When you notice your mollies stop eating, there are probably issues in your aquarium.
Hence, we recommend checking out all other possibilities before diagnosing health problems.
Minor Brown Spots on Mollies
This symptom may occur because of parasites like anchor worms.
