Do partial water changes. Add 2 - 5 drops
per gallon of
Methylene Blue. |

aquarium and other objects. Colors fade |
|
A toxin is in the water. Has any
medication been given recently? |

Do several partial water changes. Filter
the water over fresh activated charcoal. Test the tank
landscape for toxic substances. |
|
|
|
|
|
|
|
The fish have Whirling disease |
|
Treat the fish with:
Quinine Sulfate. |
|
D). Some fish remain apart from
others and darken in color |
|
They may be affected by Skin parasites |
|
Use: Praziquantel
-or-
De-Los -or-
Parinox

|
|
Are there other changes (e.g., losing weight,
pop-eye, swollen body?
Dropsy |
|
For pop-eye use
Erythromycin
If both eyes are swollen, this is dropsy and is hard to cure.
Try raising the temp up to 84 degrees fahrenheit. Use a
Doxycycline/Kanamycin combo
treatment for up to 2 weeks.
If losing weight and sunken eyes, this could be Tuberculosis.
Quarantine this fish and treat with Kanamycin for up to 30 days. |
