Potential Causes |
Treatments |
| New fish are sluggish, won't eat, hide,
& are generally distressed. |
1) Acclimation Shock - differences in
water chemistry, temperature, and shipping shock.
|
1) Check
water conditions and very slowly add about 1/4 tsp. of aquarium salt/gal, or
"StressCoat"
per instructions. |
2) Environmental Change Shock
|
2) Just let nature
take its course and have plenty of plants for hiding. Fish will eat when they're
hungry & when you're not watching. |
3.) General Behavior of Species of Fish
|
3) Check with aquarium
books & references to learn more
about this species. |
| 4) Introduced new fish to tank with predators. |

1) Toxic Shock., usually from ammonia,
nitrates, nitrites, pH, or other poisonous chemicals.
|
1) Water
should be tested for ammonia and related, changed slowly (1-2 hrs.) if necessary. Check
fish for other symptoms. |

caused by raised levels of ammonia, nitrite or very high/low pH.
|
1) Water
