The thing with the fish

I know I'm going on and on about the fishes, but somehow lately they have been more and more on my mind. Also yesterday happened something that I could call a breakthrough in my plan to get my paws on the fish. Well, it would have been a breakthrough if I hadn't, well, chickened out...
 
The staff was cleaning up the aquarium, which means the fishes were collected into a bucket during the clean up. I had the golden opportunity to get to them, since this is how close I was able to get:


Can you believe my luck! There I am, just a few centimeters away from the fish! But then it finally hit me, the fishes are UNDER the water. I'm a cat and I hate to be under water. I tried to put my paw into the water, but it didn't feel nice at all. I just couldn't go through with it!
 
I don't quite understand, everytime there is fish on my food bowl, there is no water there, only the fish. How does that happen? How do the humans take the fish out of the water? I can't understand how I didn't realise the fish were actually in the water when they were floating in the aquarium. I kind of thought that the glass of the aquarium was the main obstacle..
 
Oh the frustration and disappointment!! All the careful planning and waiting going to waste!! How can a cat get over this kind of letdown? Maybe I should turn my interest towards the birds instead... What's the catch with the birds? How should I prepare myself?
