Barb Swimming Oddly

[Hamsnacks]

Today one of my Barbs is swimming almost like its tail end is heavier than its front, so it's swimming at an angle, almost vertical with its head pointing up. But still swimming around and not going to the surface for air.
I've attached a link with a short video.

Could it be constipation or bladder disorder?
Should I just wait until tomorrow before doing anything?

No other fish is showing similar signs. Some of the Black Ruby barbs do look fatter today but they usually do get bigger and go back to normal, always assumed they were carrying eggs but maybe its something else? I bought them from a reputable local supplier that told me a few of them were "pregnant", like I said, some days they look fatter, and then they'll go back to looking normal, but first time, one of them swims like this.

Thanks

The ruby barbs has a swim bladder problem. There is not much you can normally do about this. You can try faster them for a couple of days and see if it helps, otherwise euthanize her.

Are they in pain during this time? I don't want to give up on it so soon but also don't want it go through pain just to eventually die either. Is it somewhat common for fish to get a bladder issue and it not be preventable?

It depends on whether the swim bladder has an infection, if it has popped or if it is just malfunctioning as to whether the fish is in pain. If there is an infection or it has popped, then I would assume there is going to be some pain. If it is just malfunctioning, it probably doesn't hurt, but it might.

If the fish is still eating well then it is probably not in pain.

Swim bladder issues are not that common even tho everyone on the internet says their fish has a swim bladder issue. Fish that are weird shapes like Balloon mollies, Pearlscale goldfish and other deformed fish are more prone to swim bladder issues. Ruby barbs are not commonly affected but any fish can have a problem with their swim bladder.

The main symptom of a swim bladder issue is: the fish either floats or sinks when it stops swimming. Your fish is sinking and is constantly swimming up to stay in the water column. This is characteristic of a swim bladder problem. The fish can no longer stay buoyant in the water and has to constantly swim up just to stop it sinking to the bottom of the tank.

With fish that float to the surface and struggle to swim down, this can be a swim bladder issue or it can be air in the fish's intestine. When fish take dry food from the surface of the water, they take in small amounts of air. Some fish (goldfish) are more prone to this because they are greedy feeders and gulp at the food on the surface. Dry food also has air in it and if fish eat too much dry food, they get air in their gut and it can cause them to float around a bit.

If a fish is floating about due to air in its intestine, the problem should clear up within 12-24 hours as long as the fish does not ingest more air. If fish are floating about and having trouble swimming down, then don't feed them for 24 hours and see how it goes. If it improves then reduce the dry food and increase fresh, frozen (but defrosted) and live foods.
