Odd Guppy Behaviour

[mbeer21]

I've had this Guppy for nearly 2 years, he was mature when I got him. Usually he's the most dominant of my 4 males, but today he's been hiding in the top corners of the tank, pointing up and just hovering. The other males are swimming about him as normal, but he's ignoring them. Is this a sign or sickness, or is he perhaps getting old? Or, I did move the tank last week - is it a delayed reaction to the move? (seems unlikely..)
Blurry photo attached; he's been like that for the past few hours, usually a bit closer to the surface. Other guppies are in the photo too, they're fine. He looks bloated in the photo, but he's always been that fat, since I've got him.
Ammonia - 0.00 ppm
Nitrite - 0.00 ppm
Nitrate - between 20ppm and 40ppm

If you haven't added any new fish inhabitants lately then it is most likely old age. If you did add fish recently it could be parasites or worms. Do you feed them a varied diet of different foods? Maybe try squishing up a cooked pea and have him eat it if it could be constipation.

It could be old age.

What does the fish waste look like when he goes to the toilet?
Does he look pale or darker in colour?
Is he able to maintain balance in the water?
Is he gasping, or laboured breathing?
Has he been resting for long periods on the substrate?

I haven't seen any waste from him at the times I've been observing the tank. Other than wanting to stay in that corner he seemed fine; when I gave them their daily feed he perked right up and swam around as normal eating, then went right back to his corner.
This morning, though, he's not with his guppy gang, he's hiding in my Anubias plant. He doesn't appear to be moving at all, but he's not floating or at a funny angle so he must still be alive ... looks like he's on his last legs, anyway

All you can do for him now is isolate him and try an internal bacteria medication.


Good Luck.

Hi, You mentioned to observe the color of the guppies stool. What does the color of stool tell us? Like would red or dark stool mean worms? What would pale stool, clear stool tell us? Thanks for any info!

White stringy poo can mean the fish is constipated, has a bacterial infection, or suffering from internal parasites.
Grey stringy poo the same as above.
Clear poo, the fish is running on empty due to not eating, bacterial infection, internal parasites.
Red poo can be due to feeding red foods. Blood red poo can be internal bleeding.

Hi,
Thanks for the info on stool(POO)Do female livebearers have odd looking stool prior to the fry birthing? Like stringy? Why do female/male guppies eat their fry or fry of other fish? Especially when they are fed well? You know those birthing boxes? Sometimes the fry swim right back up thur the opening space and the mother eats her fry Why does she do this?, Thanks, twofish

How is the fish?

Some animals eat there young. As for reasons why I couldn't say.

 

[mbeer21]

He seems ok today - he's not venturing too far from the corners, but he's interacting with his buddies a lot more. I guess I'll just keep an eye on him

Thank you for the update.
Good Luck.
