howdy roo..i received my guppies today i bought online from a website..i dont know if its the tank..beings this is a new and different tank (biube) so i dont know if its something about it or what..but i got 16 of them..(15 females and 1 male..) they've formed like a school of guppies..they stay in a tight formation and at the top...i dont recall any of my guppies ever doing this..could it just be maybe they were sedated a little from when they shipped them? i cant seem to find much info or others queries with biorbs or biubes...i worry about the air flow through the tube in the center..and how it affects the movement in the tank..if theres to much movement..they hang out at the top which has the most..so its like are they going to get "sea sick" lol
