Same size, but it might be activity level. I used to have a bulldog, he just sat in the corner and moved when he smelled food. My bristlenose, though, hasn't stopped moving since I got him.
Am I the only one in the world who has a bristlenose who sits under a log and doesn't move except at night when she darts out to go hide under the filter??!!!
I wouldnt have 10 neons either....i started with 6 which was fine at the time because they were tiny. They are now twice their original size and take up alot of room in the tank as they very rarely separate and swim round together.
