so i have three baby pacs. there about 2 and a half inches now. and since ive gotten them they have all lived with each other and they have never snapped at each other. but ive done so much research and it basically always says you cant house pacs together.. i just wanted an opinion on what i should do. because honestly i think there going to be fine. they never go hungry, they dont mind each other and if anything i honestly my pacs like the company of each other. i try to keep them "separated" by putting them in different sides of the tank (i have a decently large hexagon tank). but when ever i do that they just move back to the same corner and kinda huddle together like they usually do. so i was hoping for some advice/feedback on what you think i should do
thanks
