I'll try to count, I'll probably miss several, especially with the african cichlid tank and the native tank.
More than 78 freshwater fish, I'm positive I missed several.
13 SW fish at the moment.
91 total (plus whatever I missed)
------
28 species of FW fish, 13 species of SW fish: 41 total.
The number of species matters more to me than total number of fish. You can have a massive school of neons or something and it's not going to seem very impressive.
(Yeah I know we're just supposed to be counting total fish overall, but I figured I'd mention species since I at least have an exact # on that)
