Green Goo Out Of Betta Belly

[Neal]

I just done a like 70% water change and when my betta swam past the filter, some green goo came out of his body. Now he is laying on the bottom of the tank and he looks in pain... Do you know wat I should do?
Note; I have now turned down the filter, it was only turned up because I was changing water and experimenting with it...

 

[WILDER]

Is there a hole where the stuff is coming out off.
I would issolate the fish quickly.

 

[Neal]

I'm not sure there is, but I couldn't tell you for sure. He is on his own anyway, and he seems to be swimming about a bit now, maybe it isn't something to worry about?

 

[WILDER]

Where is the green stuff coming from on the fish.

 

[tttnjfttt]

I would leave his tank alone, turn out the light to reduce stress and cover the tank with a blanket if the room is light.

 

[Neal]

It's comin out under his gills and back a bit... I'm turning off the light now.

 

[WILDER]

Sounds like a bad infection to me, do you have any antibiotics.

United kingdom so no antibiotics, i think you need a vet.

 

[tttnjfttt]

can you describe it? DOes it seem like a thick liquid or thin? Is it a dark shade of green or bright green? Was he healthy before?

 

[Neal]

It just seems like a big light green poo. He was healthyish before, but now he actually seems to be fine, must of been the daze of the cold water I added that made him go to the bottom.

 

[tttnjfttt]

Did the poop normally come out of his anus or elsewyere? Earlier you said it was coming from his gills and his back.

For future reference, make sure that you keep the water temp the same when you do water changes.

 

[Neal]

No, it's not coming out of his gills, it's just like behind them on their stomach, and it isn't a poo. He seems to be fine now, but i'm still unsure, and I will keep it at the same temperature during water changes in the future. Thanks, Neal.

 

[WILDER]

There must be an hole where is coming out of, or is it coming from the scales, is it long and stringy.

 

[WILDER]

Does it resemble a parasite.

 

[Neal]

It's come off now, I don't have a clue what it was, he seems to be fine, no worries now.
Thanks for all the advice!
