I ordered 6 rummy nose and they sent 7 , the seventh one hangs out alone , seems ok , eats and all ...is it because 7 is an odd number is why he is alone ??
Thank you for the insight , his/her color is good and is eating but just hangs alone mostly , I did catch him a time or to in the group and thought oh good then later he was alone again .boxtop said:I have rummy nose. I started with 9 and after 10 months one of them died so now I have 8. What I can tell you is that sometimes they shoal together and swim in a group almost in unison and sometimes they seem to be very independent and all over the tank doing their own things individually. If the color is good and the fish is active and eating, I wouldn't worry about it too much.
When they are new to the tank, they go through a period of establishing dominance in where some of them seem aggressive towards the others. After a short time the behavior stops and then they are relatively peaceful and actually very timid fish.
