Did not know they would only get that big, thanks. But, yeah all of her tankmates are much larger than her, was hoping it wouldn't make a difference like it did.Yeah thats a regular ZZ female. The maximum size they can reach ranges between 5-10 inches. But usually around 6-7 is where they max out. The other thing that has most likely slowed her growth is her large aggressive tank mates. I saw an Oscar, Green Terror, and a very large Bleekeri. These large tank mates will also cause her to grow much slower because she is no where near the "top of the food chain" in that tank.
