I had 2 dp's in a 10 gallon tank. One of them died a few weeks ago and I want to get another but I'm not sure if it will work. The new one will be smaller. Will the older one be territorial and aggressive to a new one? I'm thinking my best bet is to just leave him as the lone fish in the tank. What do you all think?
