I'm slowly restocking my 75 gallon tank. I have a large pleco, 2 red-eye tetras, 2 grown Cory's and 1 Platinum Gourami. I just added 4 small Cory's, 4 paradise blue gouramis and 5 white skirt tetras. My platinum is chasing the skirts and the paradise fish. Will this stop after a few days? Do I need to add more platinums?
