Kribs finally paired

My 2 kribs in my community tank have finally paired,it is so amazing to see them working together and defending their teritory against their tankmates. (Hard to believe since they used to be worst enemies).This morning I was watching them clean their corner of the tank ,one of my firemouths approached them (he's twice their size) and the pair worked 2gether to size him and scare him off eventually.It seems like they are still searching for a suitable cave....So I'm hoping to get baby kribs soon
