Okay so i went to my lfs and got three Harlequin Rasboras. These little guys are great. they seem very happy and healthy, and are swimming all over the place. Anyway the first plants i got were the Walmart bulbs. I got them because everyone was saying how well they grow and easy to maintain. Apon. and some kind of plant that resembles the tiger lotus. Im really excited to watch them grow. Plus they don't really need a lot of lighting. I have one question, how long do you suggest i wait until i add some more Rasboras. I want to have a school of six or seven. They shouldn't add to much to the bioload because they are so tiny Right?
