No, they only "breathe" oxygen that is dissolved in the water. They in no way break apart water molecules.
crocodile excrete its nitrogenous waste through its cloacal opening
Clownfish are not particularlily 'helpful' to their environment. Very few species, in fact only one (Homo sapiens - mankind) strive to help their environment. Clownfish live in the reef environment, and as a by product of their behaviors and breeding, they provide food (baby clownfish) for the reef, and also produce metabolic waste that helps aglae to grow.
They produce oxygen as well as provide food for fish that are eaten by other fish. Allowing the cycle of life to continue!

Fish are consumers, because they eat other animals or plants and they do not produce their own food.
The same way a human does. by digesting food. :)
C. Hydrogen
Not enough oxygen in the water ! Fish need their water changing regularly - as their waste builds up large amounts of nitrogen which combines with the oxygen and hydrogen molecules in water to produce ammonia.
Oh, yes. In pretty much the normal fashion. A little string comes out of the back of the fish. Almost all animals excrete wastes. Fishes excrete an ammonia-based waste product.
If the questions is what is the waste product of freshwater fish, then that would be ammonia. Freshwater fish product ammonia which is excreted through their gills and into their water, to keep this poisen to a minimum you need to a filter which has bacterial build up in the media which lives on ammonia and converts it into nitrite, then another group of bacteria absorb nitrite and product nitrates. Nitrates are much less dangerous to fish and some of them are used up by plants so planted tanks are much healthier for fish nitrates however do need to be kept low and weekly water changes should do that effectively.
Betas are very aggressive and will attempt to kill the goldfish. Also goldfish are a cold water fish that produce a lot of waste which could be harmful to the Betta.
Well, fish produce amino acids, In their waste ( poo ect.. ) Butt i don't really know any other way.
As far as waste producing, this is probably a toss up between a goldfish or a plecostomus. Both produce a high volume of waste, and it's for this reason that hobbyists recommend larger tanks for goldfish.
Oxygen - that's why it's so usful to have pondweed in natural ponds where fish live. In return, most pondweed thrives on the waste from the fish, helping it to grow.
Fish poop is the common name for fish feces. If you are referring to dead fish parts which are not directly used in food, then fish waste is the proper term.
Green Spotted Puffers grow to about 6.5", but due to the large amount of waste they produce, this high-end brackish fish requires 30+gallons per fish to survive. -Hannah- GreenSpottedPuffer.net
