p%28x%29=90%281%2B1.5x%29%2F%281%2B0.5x%29
if x is the number of months+, you will have:


one month after the fish is placed in the aquarium:
x=1
p%281%29=90%281%2B1.5%2A1%29%2F%281%2B0.5%2A1%29
p%281%29=90%281%2B1.5%29%2F%281%2B0.5%29
p%281%29=90%282.5%29%2F%281.5%29
p%281%29=225%2F%281.5%29
p%281%29=150%29....the total number of fish

three months after the fish are first placed in the aquarium what is the total number of fish
x=3
p%283%29=90%281%2B1.5%2A3%29%2F%281%2B0.5%2A3%29
p%283%29=90%281%2B4.5%29%2F%281%2B1.5%29
p%283%29=90%285.5%29%2F%282.5%29
p%283%29=495%2F%282.5%29
p%283%29=198%29.........the total number of fish

six months after the fish in the aquarium
x=6
p%286%29=90%281%2B1.5%2A6%29%2F%281%2B0.5%2A6%29
p%286%29=90%281%2B9%29%2F%281%2B3%29
p%286%29=90%2810%29%2F%284%29
p%286%29=900%2F4
p%286%29=225%29.......the total number of fish
one year after the fish are first placed in the aquarium

x=12
p%2812%29=90%281%2B1.5%2A12%29%2F%281%2B0.5%2A12%29
p%2812%29=90%281%2B18%29%2F%281%2B6%29
p%2812%29=90%2819%29%2F7
p%2812%29=1710%2F7
p%2812%29=244.29......since you can't have decimal number of the fish, round to whole number
p%2812%29=244........the total number of fish
