Molly spinning around on its head!
I have a yellow molly that within the last couple of weeks has started displaying some strange behaviour. She seems perfectly healthy but has started randomly spinning around in circles, not chasing her tail but more like barrel rolling - any idea why that maybe?
Have taken some video but not sure how to upload it?
Could it be she is trying to give birth?
Been doing some research and starting to wonder if its swim bladder disease, as she is spending a lot of time on the bottom of the tank, swims slightlyto one side and seems to be going to a lot of effort to stay that way.
Put her in a breading net and she went mad - constantly tumbling trying to get to the bottom.
Hi Flambo, welcome to the forum. I have no expertise in regards to livebearers but plenty of people here do. I'm sure someone will come along shortly. In the meantime, can you share more info on your tank? The size, how long it's been set up, inhabitants, water parameters?
I'm afraid the prognosis is not good. You may want to separate her from the others and read the article at this link;
If it were Dropsy she would probably be swollen and appear bloated. Swollen areas may exhibit a 'pine-cone' appearance caused by the fish's scales sticking out. You can best see this by viewing your fish from the top. Fish may also stop feeding, appear off-colour, become listless and/or lethargic, have sunken eyes, and hang at the top or stay at the bottom of the aquarium.
Thanks for the comments.
I have a 200ltr tank thatís been established for about 7 months. All the tests for the water chemistry come back fine.
The image attached shows a picture of the tank and you can just make out the yellow molly at the bottom.
The tank has:
3 x tiger barbs
3 x green barbs
2 x red find shark
2 x angel fish
5 x dash dot tetra
3 x yellow mollies (2 female)
2 x black female (1 female)
1 x common pleco
1 x gouramie
1 x glass fish
5 x neon tetra
Recently added some new plants and started adding carbon dioxide, which maybe conincedently when the molly started acting strange.
I have not added any salt to the water as I was worried about the other fish and I read that it can kill the plants?
If you need anymore info let me know.
is the molly in question a ballon molly?........From the pic it looks like it could be, if that is the case, the genetically altered fish are more prone to health issues..........How often do you do water changes and how much?........Your tank is overstocked and this could be a contributing factor to your molly's problem.....It does sound like swim bladder disorder, but that can sometmes be hard to diagnose........
She is a ballon molly - I try to change the water by 25% every two weeks but its more like once a month or if it looks like the nitrate readings get a bit high.
Thought I might be getting close to stock limit, read 1 fish for each gallon so thought I would keep it below that?
Whats the best thing to do if it is swim bladder?
weekly PWC of 25% are recommended here is a good site for checking your stock level (fillin all the info and it will be at the bottom) AqAdvisor - Intelligent Online Aquarium Stocking Calculator and Aquarium Tank/Filter Selector
Thanks for all the help! - looks like my tank is overstocked, the link above (which was really helpful) says that it is at 172%!
The chemistry all seems to be good though - but think I might get another tank and take the load off a bit.
Looking into treating swim bladder as it seems treatable as opposed to whirring disease.
One of the things I have read that may help is adding some salt to the water - would that be ok? How would it affect the other fish and plants - any idea how much I should dose?
