You are snorkeling out in the ocean, when you come out across this sight. You cannot decide if the smaller fish is a parasite or a mutualist of the bigger fish. You decide to both do more observations on these two fish species in the wild, and to bring them back into the lab for experiments. Describe the observations you would make & an experiment you could do to test if this is a mutualism or a parasitism.

The analysis comprise in watch the conduct of each gathering of fishes. Subjectively, we can mention objective facts of the swimming examples of every creature, on the off chance that they assault one another or if the pass on. Be that as it may, this investigation will be founded on quantitative outcomes. We will observe during multi month of the quantity of fishes in each gathering that still alive. Obviously, we will give the standard states of nourishment, oxygen and light to each gathering.

We need to determinate if the two species can get by their own without the nearness of the other one. Our hypothesis would be: If both kind of fishes have a mutual relationship, the two gatherings (1 and 2) will lessen the quantity of people continuously. On the off chance that the relationship is parasitic, one of the two gatherings will have less number of people toward the month's end.
