I think your PIN is
694711
Fishplanation:
For each totally-real breed of fish depicted, take the letter from its name corresponding to the number of bubbles

Your PIN clearly is
123456
Explanation:
You're happily mixing freshwater fish, saltwater fish, building equipment, fruit and even mammals (both aquatic and non-aquatic) in the same aquarium, so you're probably - with all due respect - a person of limited wits.
It is well known that as such you're highly likely to choose a PIN of a certain style, and the example given in the linked video can trivially be extended to six digits, ending up 123456. (Amazing! That's the same PIN I have on my Stack Exchange account!)
