Introduced a tiny pleco to my tank today. Once he started sucking on the glass in a back corner, my bronze corydoras strted swimming all around him and head butted him a few times. The pleco didn't seem to care, but the cory would swim away, then swim right at him, darting away at the last second. I don't know if he wants to play or he if he's just being mean. The pleco eventually wandered into the little stone pipe I put in for him, but my cory is still darting all over the place.
The only other time my cory acted all crazy was when he was first introduced to the tank with a small school of tetras. He played in the bubbles, gulped lots of air, and darted in and out of all the plants. But he never harrassed any of the other fish or shrimp until this pleco came.
Do you think my cory is just excited to have another catfish to hang out with, or is he being territorial?
