Hi and welcome to AA.
How many L/Gal
is your tank?
The silver dollar is a schooling fish. They need schools of at least 6 of their own kind. They can quite large and need huge tank to accommodate them. The SD is probably stressing from the new additions to the tank. That was his tank and now, because he doesn't have a school, he has become defensive.
The pleco is probably a common. They can reach 2 foot in length. To keep both those fish you would need a 125gal+ tank. The best thing to do would be to rehome them both.
What other fish do you have and how many?
