Hi! I have a wonderful litlle girl who has quite a personality! She has a very distinct pattern of behavior and communicates quite nicely to me when she is hungry, happy, or angry. However, this morning when I came in she was doing something I have never seen her do. She was swimming around the walls of her (square) aqaurium flaring her little gills. She would also come straight up to the glass and do this to me. She did it again when I came back from the kitchen.
Is she angry or playful? Should I be concerned something is bothering her?
