ok i have four in my 10g, i have some hornwort and rocks in there. the problem is my 4 bolivian rams are very territorial. when one gets close to another, they start raisin their top fins, and start peckin and at times even lip lockin each other. how can i get the 4 to pair up?!?! they each have their own little corners in the tank and i wish they'd start socializin.
