Yes, they do. But here's an odd fun fact:
Freshwater fish drink very little and produce high amounts of diluted urine.
Saltwater fish drink a lot and produce small amounts of concentrated urine.

Hi!
Yes, like most creatures, they do urinate. It is part of the reason why regular water changes are so important. Fish urine contributes to ammonia levels in your tank as well as the number of fish in the community.
High ammonia levels in the tank can be avoided by a 25% water change on a weekly basis.

Yes fish do urinate. They excrete ammonia as the waste product.They are ammonotelic animals since they live in water. Ammonia requires large amount of water to dissolve.

Yes. They get rid of ammonia waste. (Hence why you keep an eye on your ammonia levels if you have an aquarium!) Depending on their environment however (salty or freshwater) they will regulate the amount of water in their body by releasing either more water with their urine, or very little water so that what they are releasing is urine 'crystals'.

Yes I know it is possible, like if you catch a fish while fishing and squeeze or step on it, fluid shoots out. I believe that this is pee, it could be sperm I guess if it was a male fish. I'm not quite sure...and they don't drink water I don't think...Hmmm good question. Ah! Find an aquarium expert and ask them....I betcha they won't know either...Maybe it's a secret and nobody knows....I'm puzzled...

Of course they do and that is why regular partial water changes are important. Their urin changes the chemistry of the water to acid and other chemical compounds form .

They have kidneys,so they excrete waste through them ,so that's urine,so yes. The stuff that shoots out when you pick them up is "milt",the fishy form of semen.
