I have a 10g with 2 balloon mollies, a opaline gourami and 1 cherry shrimp. I had to move them there to make room for my oscar that i moved to my 37g. i got a crowntail betta and as soon as i put him in the gourami was harrassing him. i come back about 5min later and the betta is flaring at him and the gourami left him alone for the rest of the day. i come back from my vaca in florida and i find the betta hiding in the cave. he doesnt come out. Whats going on? if the gourami is still harrassing him what can i do?
