What is your tank water like, ie: ammonia, nitrite, nitrate, PH & temperature?
How often and how much water do you change?
Do you dechlorinate the new water before it goes into the tank?
What do the fish look like when they die, or just before they die?

hi again
ill give you the ph and all that tomorow but i can tell you the rest
the temparature is around 24 and 26
i change the water every week and take out 20% of the water
i do dechlorinate the new water
when my pandas died they were on the floor on their sides but the albinos floated to the top
my last albino was caught in a plant though
cheers

do you do a gravel clean when you do a water change?
did the dead fish have any red patches on them, or were their fins split?

 

[dill]

i do clean the gravel when i change the water
not sure what you meant about fin splits but they didn't have red patches

 

[fishes1995]

what do red patches mean?

 

[Colin_T]

red patches can indicate poor water quality or a bacterial infection.

split fins = fins that are not normal and have been damaged, ie: split or frayed.

 

[dill]

oh okay
they didn't have split fins

Does some food drop down into the gravel? Because corys won't eat from the surface like most fishies, they need to suck food off the substrate.
