Well that escalated quickly.
Now that I am back online and can respond, I have a few things to say.

Depression is a mental disorder in which neurotransmitters do not release properly or do not release enough into the blood stream.
If you look at what a fish's brain ACTUALLY looks like, you can get some sort of idea on how they work.
They DO NOT have any cortical folds in their cerebrum, which is a tell-tale sign of overall intelligence. Higher mammals such as humans, chimpanzees, and dolphins all have cortical folding in their cerebrums. Cats and dogs also have cortical folding. Frogs, most birds, and fish have little or no folding whatsoever.
A fish's cerebrum and cerebellum guide it during voluntary actions such as eating, swimming, eye movement, etc.
The brain stem including the medulla oblongata control functions such as breathing, body temperature, and various other bodily functions we make no conscious efforts to do
Fish also have a olfactory and ocular bulbs to smell and see (chemio-receptors)
This is the sort of info I want. I have very minor experience studying functions of a brain and unfortunately have only been able to study the functions of the human brain. My very brief, limited, understanding on how the human brain works stems from a university course I once took on the pharmacology of illicit drugs and how/why the human brain reacts the way it does. I have never been able to study animal, specifically fish, brains or how they differ. My limited knowledge is hindered by my non-scientific background and I would wish to expand more into this.
Thank you for giving me words to more specifically search for. Do you have any articles you would recommend on this blurb you described or diagrams from scientific sources? I would love to examine this further but would like a simpler source, so to speak, that I can understand with my limited background.

How do scientists rank fish intelligence? Why is the mormyriade more intelligent than, let's say, a tuna? I am not familiar with this species and I think using it to compare to betta splendens would be interesting.
In general: Does anyone have a scientific database that has good articles/research in ichthyology? I need a starting point and I need to become familiar with the basics so I can relate them and apply them to betta fish. I would not even mind comparisons within the betta species (i.e. betta splendens VS betta imbellis). I find this sort of thing fascinating.
Chocolate: I have to ask that unless you can support your opinions with scientific fact, that you do not post as if your opinions are fact. It adds confusion to the thread and the point here is to be able to identify information from scientific sources with support. I do not mind if you comment and discuss along with everyone else but I feel as though you are derailing the point of my thread and I ask that you refrain from doing so and keep an open mind to facts and other opinions. Thank you.
