I have three Peppered Cories now and two of them stick together 90% of the time and the other one only spends about 30% of his (her?) time with the other two. is this normal?
I agree with you.Sometimes one of mine go solo and while the other two hang together. Sometimes they all stick together. I'm sure it's fine unless it's acting distressed or the others are picking on it, which I can't really imagine with corys.
