Re: Blue acara and others?
Blue Acara are often confused with Green Terrors. Hopefully you will get the Acaras. What ever you get to put in with them will have to be as large as they are as they will pick on smaller fish. The Gourami may be ok, but the Knife probably won't unless it has a very secure hiding place. If the Knife can stay out of sight during the day it may not be picked on as it is a nocturnal fish.
I got off the porch and ran with the big dogs. Now I can't get back on the porch!
