Actually having said that you may not have the space afterall..
6 mollies = 3 inches fully grown, 18 inches altogether and 18 inches filled.
3 tigers = 2 inches each, 6 inches all together, now 24 inches filled.
3 scissor tails, 4 inches each, 12 inches together, 36 inches filled.
You're probably a bit over - I forgot how big scissortails grow. They don't tend to stay around each other the less there are in the tank and tend to be more shy. Can you have a search on google and see if they actually are scissortailed rasboras? They may have been mislabeled at the store and therefore I could be giving advice for a totally different fish! I just assumed they were these from scissortail zebra fish.
