betta urine?

[KageBunshin]

Last night before going to sleep, I gave my CT a good flaring session after his water change. This time though, when he was flaring he ecreted 1-2 drops of some yellowish/brown liquid from the front part of his body (Most likely is anus) that quickly dissapated. Is this Betta urine? or is it some kinda of other bodily fluid? Has anybody witness this before?

Yea, that would be his anus. It is located between the ventral fins. All I have ever seen come from there is stings of poop.

i have seen it too. i have always thought it to be urine.
the first time i saw it, i freaked out and thought my fish had diarrhea

 

[KageBunshin]

lol yeah, I thought he was bleeding at first.

awww, you got him so excited that he tinkled all over the place. My dog does that

My readings stated that their urine is not visible. Unlike us, they do not build up urine in their bladders, but rather, like our sweat, excrete it as they breathe out...

Interesting. Post a link if you would ,sir. Is it pertaining to your average tropical,or a betta in specific?

FECES!!! i never even knew fish have urine. i always thought freshwater fish try to get rid of water from their body instead of taking it in. and saltwater fish try to take it in?

The body fluids of the fish have a weak salt concentration, but freshwater has a significantly lower salt concentration. Thus what will happen is that water will tend to move into the fish across any semi-permeable surfaces. The main semi-permeable membranes exposed to the environment are the gills and the gut. However, not only is the water tending to move into the fish, but the salt ions tend to move out across the delicate gill membranes as well, leading not only to water uptake but diffusional salt loss also.

So we can see that a freshwater fish is constantly fighting an influx of water and a loss of vital salts. If this were left unchecked the fish would soon die. Freshwater fish have evolved mechanisms to deal with this: they have extremely efficient kidneys which excrete water very rapidly. Also, to deal with the salt loss from the gills the efficient kidneys reabsorb salt from the urine. The gills take up sodium ions in exchange for hydrogen ions and chloride ions for bicarbonate ions, thereby taking up salt from the environment and removing unwanted ions from the blood. (Both hydrogen and bicarbonate ions will cause the blood pH to drop if they are allowed to accumulate.)
