I say anywhere from 6-8 thinbars. They dont get as deep bodied as the others.
As icthyophile stated, a bigger group does encourage swimming and socialism activity. I noticed in my tanks that the more you have they tend to actually school together. Good luck with your tank. Remember to do huge water changes and have lots of bio. I personally think that thinbars are by far the most susceptible to disease, especially gill problems.
