Step-by-step explanation:
Total spotted Total stripped

Golden spotted Golden stripped
5 0

Spotted remaining stripped remaining
3 13

1st combination
Pink Spotted Pink stripped
0 7
--------------------------------------------------------
Spotted remaining stripped remaining
3 6
[as 3 spotted fish are
remaining must be
Stripes and spots
[MIX FISH]
on a single fish]
(3 subtracted )
stripped remaining
3
Total fishes= 5(Golden spotted) + 7(Pink stripped) + 3 MIX FISH + 3(stripped remain)= 18

= 19 fishes
