Hello All,

Thanks for all the great advice I have received over the last month. My 40 gallon tank is cycled I have done the water change and waited 24 hours. Today I have added 4 peppered corydoras but I have a question.....I cycled my tank with fish flakes and during the 75%-90% water change I did yesterday I really didn't vacuum up the flakes that have been the important source of ammonia over the past month. The corys are in hog heaven right now going to town on all the scraps at the bottom of the tank but I am concerned that maybe they are over eating. Does anyone have any good advice on the subject? Thanks!
 
Okay, but will the Corys eat themselves to death if there is a substantial amount of flakes on the gravel? They have been doing nothing but eating for the past 2 hours. Is that normal?

They will always try to forage the substrate for food. It's normal but the food supply must be put to limits as too much food often causes digestive problems.
 
Cories will pick around of the bottom all day long .....Just because they are doing it doesnt mean they are eating anything...they are just always on the hunt for it ;)
 
Gravel vac the flakes up; you don't want the new cories over eating.

Also, you said you did a water change and waited 24 hours... Did you check the parems with a liquid test kit? If not, do so right away.

When I do a water change I always vaccum. Why remove water when you could be removing waste also? I have sand, but ppl with gravel should really stay up on vaccuming.
 
overfeeding isn't the only problem - eating the rotting food isn't so great, and the leftovers are going to keep putting out excess amounts of ammonia, as well as potentially growing some fungus if the bacterial levels can't keep up with the ammonia produced by both flake and fish.
