Hi all,

Can anyone help me with this: I've been unexpectantly given the job of
fish-feeder during a holiday, and the owners aren't reachable. Now I have
little knowledge about fish, and how to take care of them. Can anyone
identify the 2 types of fish swimming in this tank (see url's below), and
give me some clues as to how much to feed them? Today I took some food
between my fingers, and 'crushed' the food into the tank. I did that about
4 - 5 times.

Any help is much appreciated, especially by those fish.
