So I have a 20g tank currently with a male swordtails and female gbr. I will be adding 2 or 3 female swords soon and maybe 1 or 2 more rams to see if I can get a pair. I added 5 julii cories today and she will not leave them alone. She chases them over the tank. Do I need to remove them and put them with my other 5 juliis in my 55? Also if I do have to relocate them, will it be okay to not have a "cleaning crw" for now? I have 2 BN plecos in my 55. Would getting 1 for the 20g be a good idea?
