Spiralling/spinning paradise fish
I've got a new small paradise fish. He's about 2-3in long. I got him 9 days ago. He's been very cautious, hiding under plants in his bowl. I've been feeding him frozen bloodworms. This morning, I managed to convince him to take some betta pellets. He chewed on them and spat them out, so I'm not sure how much he actually ate.
Tonight, he's doing a lot of spinning and corkscrewing. He can stop still in the water and then shoot off in a straight line, but then he'll go down to the bottom of the bowl and spin around. It's almost like he's itchy and he's trying to scratch himself.
I've been reading about swim bladder problems and parasites. I can't see anything visibly wrong with him, apart from the strange swimming. I've put in a heater to raise the temperature a few degrees - I've read that's good for infections.
Is he actually flashing against surfaces?
Here's a video:
In the video, you can see that one barb swim up to the gravel near the front glass and, in a quick motion, rub itself against the gravel. It later does it against the decoration. This is how fish "scratch itches" caused by external parasites. Is that what your paradise fish is doing?
thanks for the response.
He's been spinning (several times at once) against the bottom, but also in clear water, where he's not in contact with anything. It doesn't really look like the same behaviour, unfortunately.
He also tends to swim on his side for short distances. If he just did it occasionally, I'd think he was just being playful. I'll try to take a video to show the behaviour.
How about this?
This post has more information about the disease:
He might have an advanced case of that. The poor little guy has deteriorated a lot even in the last five or six hours. Here's a video I've just taken: http://www.youtube.com/watch?v=yJo_kIOr6UY
I've removed most of the plants to make things easier to see. The white thing at the bottom is an O2 block that's slowly dissolving.
He seems like he's struggling to keep his tail down - it might be too buoyant. I've done a 50% water change (parameters are still fine) and chopped up a boiled pea, which he tried to eat but spat out.
Poor guy! That does look like whirling disease to me. I've never had to deal with it myself, so my best advice to you would be to keep your water quality as pristine as possible and follow the advice in the post I linked to earlier in the Diseases sticky.
Sounds like there's no cure.. I euthanised him last night. He was thrashing around until exhausted, and then lying motionless on his side at the surface. I'll throw out everything that was in the bowl and soak it in bleach to make sure there's nothing left that could be carrying the disease.
Very sorry to hear that. It's always tough watching fish succumb to illnesses like that, especially ones where you can tell that they're in obvious discomfort. I think euthanasia was the best course of action in this case.
This has got me thinking about tubifex worms, as apparently the parasite that causes whirling disease is associated with tubifex worms. I think the frozen worms are probably fine as they're flash-frozen, but it definitely has me re-thinking feeding live blackworms, which are a type of tubifex worm.
