Ok, I've only been back for 6 1/2 months after a 22 year hiatus. 1st go around I had a 24" zebra that ate 2 to 3 times a week, and let me know when he was hungry.
Now, I have a predator tank with all large fish, and the snowflake. She eats every day, 24 or 25 days in a row. When I get home from work she is waiting at the end of the tank and starts swimming around when I get water to defrost the food. She eats 2 large pieces of shrimp or 2 silversides, soaked in garlic and Selcon. I feed the fish before I feed her, and she comes to the top of the tank every time to get the food.
How much is too much? I love her activity and her appetite. I just can't believe she eats so much!
