I don't know what has happen to my tank it is 55 gallon been up nov04. I cleaned the bottom of the tank with the vac thing (python). It has been about 4 days ago I have lost about 5 fish to death (guppies, molly) in the last 4 days. The cories are staying on the bottom of the tank but when I feed them they run and eat and go back to the corner of the tank again does anybody know what might be going on the amiona is 0.

Cories are a bottom dwelling fish, so having them chill at the bottom is no big deal. What is killing the other fish? Any specific kind of disease??

Byez!

Are you suggesting that there has been a change in the cories behavior? If so it would be helpful to know what their behavior was like beforehand. Also, to properly evaluate any issues you might have more information is needed.

What inhabitants are in the tank?
What is the water temp, pH, nitrite, nitrate?
How often do you feed, change filters, vacuum?
Have you made any changes recently?

The more detailed your description is the more likely we'll be able to help out. From what you said I can only say that you cories are behaving normally. They are, as Sahara said, bottom dwelling fish.
