New Tank, Unusual Cory Behavior?
New tank. My folks got it for my son. We started with 3 lamp eye tetras for a week, per the pet store, and then added 3 neons a cory cat and a dalmation molly. The molly had 5 babies, ate 3 of them, and then we isolated them, The mollie later died. This is all in the course of two weeks. A water test revealed high nitrites yesterday, but everything else in line. Completed about a 50% water change yesterday. All other fish behavior appears normal.
Up to now, the cory cat scaveneged around the bottom, the rocks, etc, "doing his thing". Tonight he is racing up and down the sides of the glass, back and forth. Have not yet completed another water test, as was advised to wait 48 hours to retest all. Am unsure if it is normal for him to do this, or if this could be related to the nitrite problem. Maybe he does this when we're not looking at other times, but we haven't seen it before. Thoughts would be appreciated.
