Your BN will grow like the clappers! I got my first one about 6 weeks ago and she was so tiny - now shes 4 times the size and a beautiful fish! Make sure you give yours a good diet and dont leave them to feed on just scraps and algae. I feed mine plec wafers, peas, courgettes, peppers, cucumber, sweet potatoes, flake food, frozen blood worms & daphnia and she also likes the crab pellets I put in for the shrimps! (who also adore peas!) So far she has turned her nose up on spinach and lettuce!
