Aquarium Advice Regular
I just started giving my corys pellets - wanted to try them. Until now they seem to have been doing fine eating leftover food from the others. My concern is that they appear to be going uneaten - just fished out 2 last night with a gravel vac because my nitrates were too high for comfort (20ppm when they have been more like 5ppm). I was advised to give 2 per fish (the pellets look like rodent droppings). As of today the nitrates were still up there - should I be concerned or is 20ppm really nothing to be concerned about? I'm ready to do another water change but all the other parameters are fine - 0's for everything else. I'm thinking I should wait until I get more corys (I have 2 right now) before I use them again?
