Aggressive Pleco?!?!

[Dovii dude]

I have a 4 inch Regular Pleco,he is in a tank with 3 Silver Dollars.Yesterday i bought a 5 inch Jag,the Pleco chases the Jag alot is this normal??At 1st i was worried about the Silver Dollars being chased by the Jag,but this isnt something i was expecting.

how long they been in the tank together? things may settle down. provide lots of shelters. just hope the plec hasnt "tasted" the jag
