Do plecos and corydoras fight?

Question

I currently have a 9" pleco and am thinking of getting a couple corydoras will this be a problem

Answer 1

plecos are peaceful and corydoras is not aggressive

Answer 2

Pleco are usually peacefully to other bottom dwellers...the only other possible exception is other Plecos. Plecos, if in with other Plecos that have grown or are bigger...may fight for territory...It all depends on the size of you tank and the hiding spaces available.  But usually they are peaceful.  

I have yet to see aggerssion to Cories from Plecos...but make sure you have a school of at least 3-5 Cory Cats.  3 is a good number, but 5 is better.

Depending on how big you tank is...and the fish population you have now...results in the amount of Cories you can get.  But I would not expect your Pleco wont mind and will remain peaceful.

Best of Luck!

Answer 3

most likely not. Corydoras and plecos are relatively peaceful community fish. I have had my corydoras and my pleco together for 4 months now and i have never seen them ever fight or chase each other around. Just make sure you get at least 4 corydoras. They do better in groups and are way more active. By far, one of the coolest fish i have ever had.
