Sorry, I'm laying on the jargon. Digital Single-Lens Reflex. SLRs are 
the classic kind of camera where you can change lenses. They tend to 
have better image quality than all-in-one cameras, but to realize their 
advantages you need to purchase a number of lenses and change them out 
as the situation dictates. 

My camera:

Typical DSLR:

The reasons why all-in-one cameras aren't quite as good (in absolute 
terms) as DSLRs are numerous and complex. But you can boil it down to 2 
things. 

1. Sensor size: the smaller the sensor, the worse the image quality, 
especially under low light conditions. DSLRs have bigger sensors than 
all-in-one cameras. (bigger lenses, more glass, more expensive too...)

2. Better lenses: A lens that can do macro up to 10x is going to have 
compromises compared to a set of 2 or 3 lenses that cover the same 
range. 

That all said, if all you want to do is take aquarium pictures, a DSLR 
and macro lens is an affordable way to take great pictures. 

But that is probably more than you wanted to know. :)
