Have you checked the water quality?
Guppies are very sensitive, for example. Once I had very high nitrite in my
tank, also had some ammonia. Bought a few guppies, by the next morning they
were dead. Than, I begin investigating what happened by testing the water.
Ammonia can rise very fast, mostly in new tanks. 3 weeks is a long time and
if the fish is all ready sick, you have to treat them with medication.
You have to keep your Nitrite under 40pm and try to keep it around 20 ppm.
Ammonia should be 0 ppm.
In 3 weeks, if you over feed the fish, can go to 100 ppm, means have to
change all the water out.
