The word "complex" is usually used to indicate a fish's sexual preference. Most fish are heterosexual, but if the fish has any other preferences/fetishes then it is considered complex. It is often considered a derogatory term, so be sure to not call a fish complex in the prescene of a biologist.
In general, vertebrates possess more complex digestive and nervous systems, as well as higher levels of thinking than invertebrates. They're complex animals because they're more complex than invertebrates.
Fish, like humans, have kidneys which regulate the water and salt content of the body. This process is often referred to as filtration, though in fact it is a combination of several complex processes.

Fish can fish for fish, because anglerfish can fish for other fish.
Three fish are considered a mess of fish.
A fish is multicellular, as is any complex animal.
Yes, it is correct.

A trout is a fish, and as such is a complex organism. And yes, the trout is multicellular.
Well they have limbs and lungs, which I would consider more complex.
In general, vertebrates possess more complex digestive and nervous systems, as well as higher levels of thinking than invertebrates. They're complex animals because they're more complex than invertebrates.

Not very! It is actually the dumbest of all the sharks.THat`s a myth. Sharks have very complex brains bigger compared to there body than most fish.
A group of different organ systems forms a complex organism, such as fish and mammals.
No food makes you stronger. Foods with high complex calories and protein, combined with exercise makes you stronger. Most fish have little to no protein, and a medium amount of complex calories. Try spaghetti with meat sauce, pork chop, or granola bars for high protein and complex calories. P.S. There are simple calories, and there are complex calories. Things like pop tarts have simple calories, while spaghetti or pork chops have complex calories. Simple calories last shorter and leave a big "crash" after it wears off. Complex calories last very long and give you a very minuscule drop in energy.
Yes, but their senses are not as complex as mammals. Studies point towards fish feeling pain to a certain degree, but as far as emotions are concerned, they are much more basic than humans.
You will need to set up a (very costly and complex) Tropical Marine Reef Environment for the fish and include a live sea anemone (for the fishes home). It will have to be fed several times daily. It is not easy to keep Marine fish alive.
