Pleco Chasing Corys

[Faythee]

I have noticed my BN Pleco has been chasing my Corys around. He bumps into them making them scatter. Is he able to hurt them ? Do you think this stresses my Corys. They do spend alot of the time huddled in the back corner

BNs are quite boisterous.

How big is the tank? Make sure the cories have lots of hiding spaces.

Yes he is and not shy at all. The tank is 30x12x18. I was wondering if 5 Corys was too many but I know they like to be in groups. They have plenty of hiding space, which is why I don't see them as often as I like.

Ok, tank size is fine however it is not huge so that means not so much room to get away from each other.

Are either the cories or the BN new in the tank? My BNs seem to have an obsession with harassing any new fish for a few days and then they give up and leave them alone.
