So i just got two purple cichlids. Im realizing that one of them is picking on the other. They are both female. They are living with male guppies. I read that if you simply put the aggressive one in time out it may help. Shes currently sitting in time out. And immediately everyone in the tank seems happy. My guppies had all been hiding at the top and the lesser of the two cichlids was conatanly being chased and now she is content also. My question is how long can i keep the bully in a holding cell for lack of better words lol. Should i return her to the store if she is still being mean? Help!!
