I DESPERATELY NEED HELP!!! If anyone knows the answer to my question, please be kind enough to respond as quickly as possible. I'd greatly appreciate! Namely, I have 2 angelfish. They're about 1 year old and approximately 4 inches long. They're in a 30 gal. freshwater tank with 12 neon tetras and an algae eater. My problem is that they constantly fight with each other. When they were younger this never happened. However for the past couple of months this fighting has been relentless. The slightly larger one seems to "dominate" the smaller one. It will peck the smaller fish most of the time, and attack it more aggressively during feeding times (often not allowing it to eat at all!). I tried to separate the two fish - putting the more aggressive one in a 10 gal. guarantine tank for a couple of days. This did not help. I know that the temperature and the overall environment of the tank is appropriate for the two angelfish. I have no idea what might be causing this problem. The fighting seems to never cease. Can anyone please tell me what the possible cause of this behavior might be, and ultimately, how to stop it? Any comments will be greatly appreciated. Thank you.
