I just got another 10 gal. tank and was thinking of dividing the tank. One of our females in the sorority is rather aggressive and very much trying to eat all the food all the time.
I don't want her alone in a 10 gal. setup and thought about dividing the tank into 2.5 and 7.5 gal sections with her in the small area and adding the delta CT I have in a 5 gal quarantine tank in the big section with about 7 neon tetras. I checked Aq-Advisor and from the filter capacity I am all set, but I am not sure if it is okay to have 7 Neon Tetras in an area smaller than 10 gal.
