I've collected data on the number of individuals of seven species at three different sites and want to test if there is a statistically significant difference between the three sites. The numbers are too small to use Chi square and I cannot make a 2x2 table for the Fisher's exact test. Are there any statistical tests I can use?
If it helps my data is below

Species Site 1 Site 2 Site 3
1 8 7 3
2 0 0 1
3 0 8 8
4 1 1 1
5 1 0 0
6 0 2 1
7 0 1 1
