Ok so I've had a common pleco. in my community tank for approx. 3 months now. I got him because I had a brown algae issue which he cleaned up nicely.
I thought he was a shy, docile creature since I've only seen him on rare occasions after lights are out and he always ducked back into his slate cave when we would put our face up to the tank to say hello.
My fish tank erupted with insane activity all of a sudden. My pleco had come out and was zooming around the tank which completely freaked out all of the other fish. He was moving so fast I couldn't even tell if he was actually chasing any other fish or just randomly darting around.
After that, all back to normal. He's hanging out in his cave and as far as I know, hasn't bothered the rest of the tank since.
Has anyone experienced this too? I'm wondering if this is the start of aggressiveness or is he just a nutcase??
Puzzled by this behavior. Sorry for rambling :0
