My experience with SAEs has also been that they eat voraciously-- both algae
and introduced food. My SAEs are now at least 3.5 to 4 inches, and they are
always scouring leaves-- especially around the edges-- for algae. This even
when I feed twice a day-- once with brine shrimp, and a second time with flake
food.

My tank temperature is about 78 degrees F. I wonder if that could affect their
appetite.. What is your tank temp?

These are the greatest fish! They are always good natured, and they are fun
to watch. I still have to truck off to Buffalo NY to get them, since they are
hard to find in the Detroit Metro area. (I've had to replace a few due to a
disease outbreak a few months ago, but some of my SAEs are now a couple of
years old.)

(Anyone know of a source for SAEs in Detroit?)
