An aquarium holds an equal number of clownfish and blowfish. 26 of the blowfish stay in their own tank, and the remaining blowfish swim into a display tank.  An equal number of clownfish join the blowfish in the display tank, but then a third of these clownfish swim back into their own tank.  If the aquarium holds a combined total of 100 fish, how many clownfish are now in the display tank?
Give me a clear explanation.
