Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
Jason has six fish in his aquarium. He realizes that every day the number of fish doubles. On the third day he takes out one-third of the fish. On the fifth day he takes out one-fourth of the fish. On the seventh day he adds 15 more fish. How many fish in total does he have?

### Response:
 Siku ya tatu ana samaki 6 * 2 * 2 = <<6*2*2=24>>24.
Siku ya tatu anatoa samaki theluthi moja, 24 * (1/3) = <<24*1/3=8>>8 samaki.
Baada ya siku ya tatu, ana samaki 24 - 8 = <<24-8=16>>16.
Siku ya tano ana samaki 16 * 2 * 2 = 64.
Siku ya tano anatoa samaki robo moja, 64 * (1/4) = <<64*1/4=16>>16 samaki.
Baada ya siku ya tano, ana samaki 64 - 16 = <<64-16=48>>48.
Siku ya saba ana samaki 48 * 2 * 2 = <<48*2*2=192>>192.
Baada ya siku ya saba, ana samaki 192 + 15 = <<192+15=207>>207.
