Help needed in reframing a sentence. - (Sep/21/2012 )

I am writing my first paper about neural activation but i am stuck at a sentence and i want to reframe it so that it looks better.
The sentence is:
''A pair of fish was divided by a one sided see through mirror wherein a big fish could see a small fish in the first tank followed by a small fish seeing a big fish in the second tank and lastly a big fish seeing a small fish in the last tank for five minutes before interaction''

Can someone help me reframe this sentence? Or do you think is the sentence correct? I would like to make it short

Sorry but I'm lost. You've got three different set ups? Because the last one sounds the same as the first one?

And do you mean one-way mirror?

"Pairs of fish were placed into tanks and separated by a one-way mirror for 5 minutes prior to recording interactions. Set ups were such that either only the big fish could see the small fish, or vice versa"

And I think it would be helpful to include a diagram (that's what I would do )
