Lets first see someone recreate the same numbers without having the same fish.

You seem to have a conceptual problem of distinguishing between random and reproducible.
If all the fish tend to huddle in a single corner it would be hard to reproduce - but the numbers you'd generate would be clustered around that location's value generation.
Thus, if you were using this to run a lottery, one would be wise to bet on numbers generated due to their clustering. However they slosh around in the cluster could make the numbers unpredictable but the tendency for certain values would increase. It could be irreproducable but the generated numbers would not be random over the number space.
You'll have to think this through for yourself - it's hard to express the difference.

Yes, but not in a predictable way, and you can choose which part of the picture to use - so you could simply cut of the places where they cannot be (like above the waterline).

For me "not predictable" is the same "not reproducible" but still not random.
His comment is still valid

Point is that it would be hard for an outsider to recreate the same random number.

Yes, that would work. Many scenarios like the one you specified are excellent source initialization for RNGs.
I have seen some that actually get the daily temperature, at given point in time, and add that to the mix too. PC temps have been (still?) used.

That was a nice Flash Fiction piece. 
You could do a book of these called, That Evil Cat!, and they could all end with the line:
"Who let that cat in here?"

Two things blow up your theory (although I love the joke).
1) My wife hates cats, and our dog does too. There would never be one in the house, not alive or for long anyway.
2) The aquarium has a lid, and even if by some totally, small, approaching 0, chance a cat did get in, its' attempts to get at the fish would only increase their random movement in an attempt to get away.
Nice!

Creatures with even a trace of intelligence will not behave in a random manner, whether alone, or in groups (wherein they react to one another).

Wasting your time.
Model the female thought process instead. Truly random.
If you can keep your head while those about you are losing theirs, perhaps you don't understand the situation.

Too True!
Also totally impossible in my experience.
My wife came with a manual.. but it the pages were all blank

If you were to take the camera and take a picture of the aquarium, and then calculate a hash of the resulting image file...would it really be any less "random" than applying to it the subsequent algorithm you intend to create?

How random does your number have to be?
I usually settle for the time in ticks; for the one-time-pads I usually use a completely-unrandom movie. Big blob, lots of data.
Any particular reason why you want a "true" random number?

Honestly, I was more interested in the replies I would get.
I seem to have received both a quantity and breadth of replies way beyond what I expected.  
They span from supportive, to critical, to informative, from serious to hilarious.
It seems there is a tremendous amount of interest on this topic in the community.
Also, I am at the point of planning what to do when I finally give it all up. (Retire, shudder!)
Also, I could use another reason to keep the Aquarium.
BTW: I expected someone to mention the bubbler as a source of random input. Someone mentioned the bubbler but not as a source, only that it caused the fish locations not to be random. (I disagree with that.)
BTW: I thought someone would come up with the fact that playing GILLbert & Sullivan tunes would be greatly appreciated by the fish, causing more or perhaps less random behavior. and more puns of that nature.
Finally, I thank you and everyone else that replied to this post.

You'd have more than random number failure to worry about.
Your wife / significant other would be very, very angry.
Also a really bad smell in the house.
