Something Fishy T e cages are all in place around the corals. You start herding fish into the cages. You chase them with hand nets. It’s not an easy job. T ese fish


are slippery. Each cage will hold a diff erent kind of fish. You and your partner put two kinds of fish in the last cage. You want to learn which fish eat the most algae. As you are working, you hear a


snapping sound. You see shrimps on a sponge. T ey are snapping their claws open and shut. Pop! Pop! So that’s the sound you heard last night.


Checking Your Work You watch the cages and take careful notes for the rest of the week. T e fish in the first two cages eat some of the algae. T e last cage with both kinds of fish has the least algae. T is means healthy reefs need more


than one kind of fish eating algae. T is is a discovery you can share with other scientists. Before you know it, your 10 days


on Aquarius are over. A new team of scientists will come to take your place. You wonder what these scientists will learn on Aquarius.
