See I have guppies, and when they are nearing birth / during birth you can see a clear fluid coming out i'm a small stream so to speak from the anal area. I've always figured it is some type of embryonic fluid or simply much like a human before birth the mothers water breaks I have been looking at it like that.
However yesterday I thought I saw my male doing it too. It was however a much smaller amount and not for a prolonged time or anything so I have just been wondering. Sometimes I have seen females (pregnant and non) do it also which has simply made me wonder Posted via Mobile Device
Fish get rid of ammonia via the gills. However, it's done by passive diffusion. That means that the ammonia concentration of the fish can not be less than that of the water
As a human nurse I think I am looking at comparisons of humans to fish a lot hence my "like humans do" analogies but i'm sure there is some form of explanation. Posted via Mobile Device
Lol the brown is poop and white is urine equivalent in birds I think.
So what is this fluid I am seeing come out. Urination not ammonia related? Posted via Mobile Device
the do, and especially freshwater fish, must excrete urine, but not as the primary way of removing nitrogenous waste as has been mentioned, but as part of osmoregulation
So that is most likely what I an seeing? If you imagine a petrol slick how it looks like thick water almost that's the best way to describe it that I can think of right now that might be the stuff. Posted via Mobile Device
They do, very prolific pee-ers, up to a third of their body mass per day. It's not something that many like to think about when playing in the tank water. :roll:
I said that to my fiancé and he laughed at me the other day and said I was playing in pee!
Still don't know of that I'd what I am seeing have had no confirmation or otherwise but who knows... God knows.when ever I have a chance i'm on the chair infront of the tank admiring its occupants but it is certainly something you would have to look closely at to see Posted via Mobile Device
Yah, just think, if you peed out a third of your body weight each day, it would most certainly look like water. I know when I was drinking a Canadian gallon of water a day, well.... you can figure out the rest.:roll:
This is one of the reasons that water stability and correctness for the fish is so important.
Haha I don't know how much a Canadian gallon is, I didn't even know it was different from a standard gallon
Also most likely because we use the metric system.
It looks like thick water but the petrol thing my analogy is like the way you can see it you know how its almost shiney like an oil slick in the ocean but its clear. Looks thick though Posted via Mobile Device
the urine is very dilute with less solute conc than the surrounding water, so what you are seeing is likely due to light being refracted at the boundary of the different solutions, the effect of which diminishes as the two mix
I don't know if there is a significant difference between species when it comes to urine released, since it is, as Quantum mentioned earlier, related to osmoregulation. I do know that tetra can expel this much daily.
I see, we don't use gallons here really. So I wonder when packages here say dosages would it be us or imperial? I would think imperial but perhaps not Posted via Mobile Device
The North American aquarium industry seems to use US gallons. I doubt it makes that much of a difference when using supplements or treatments as most seem to "allow" for three, four and five times overdosing levels anyway. I suspect that it is not an exact science.
I would think so, my guess their pee is clear of course because of the water they drink and filter. If you drank water all your life or for one day you will pee clear. So my guess is that they do.
