Is 20 gallons enough for 2 aggressive fish?
Edit: I would however love to add a clownfish to my aquarium if my damsel won't bother it and vice versa. My blue devil dosen't go near the area with strong current often and maybe the clown can reside there if it can tolerate the mildly intense current. How would a clown fare with a damsel? Will they fight each other too? i understand your friend was sucessful but how big was the tank? Also, I know I can increase hiding places, but I would actually like to see the fish too
Thanks.
