Weird Growth On Black Balloon Molly

[Skellie]

Hey guys,Have an issue with one of my mollies. It seems to have like a white cap on the end of its bottom. Its hard to explain but have attached a video as you couldn't see it on the pictures.The fish is still able to excrete and stuff normally, just looks a bit odd. It doesn't look like the pictures in the pregnancy thread so wasn't to sure what it was.The tank mates are another black molly, 4 guppies, 2 Opaline Gouramis & 3 little fishes i keep forgetting the name of! (you can see one at the end of the clip on the right)Is this a cause for concern?

I couldn't upload the video for some reason but have taken a screen grab.

It seems to be getting bigger!

This looks like a fungal problem in the gonopodium, the gonopodium is the breeding organ on the male.

The best treatment is myxazin, melifix or salt treatment.

What is your water quality like?

• ammonia
• nitrites
• nitrates
• pH

How often do u do water changes?
How much water do u change when you do a water change?

Had the water tested on Friday and the Nitrites were high, so was told to do a water change. Did one yesterday about 20%.

Still waiting for my testing kit so not sure what levels are like today.

Would rock salt work?

EDIT:

Took another picture:

If your local fish shop admitted that your nitrites are high, you need at least a 50% water change or even more. Anything less is just playing with the water, not taking care of problem chemistry. Aquarium salt is not needed in your tank. Although there is some evidence that plain salt can help deal with small amounts of nitrites in the water, the amount of salt means there is no need to buy any aquarium salt for the purpose since a few shakes of a salt shaker would be plenty for most fish tanks. On the other hand, it is always better to remove the nitrites than to try to control the impact on the fish by adding chemicals. If you do a 50% daily water change until you get your new test kit, I suspect your fish will look much better than they have been.

Thanks for the reply.

The shop suggested 1/3 water changes every other day. I did a bit more than third (40% ish) yesterday, would you recommend doing another today aswell?


UPDATE:

The bulbous bit has fallen off! There is still white residue and it looks elongated but not as bad as before.

What would the best treatment method?

Water change? How much? Any medication/salt? Quarantine?

 

[hughessomefish]

i would do what oldman47 says personally he is very very experienced

 

[Skellie]

So 50% water change is the way to go?

Just want to make sure as i was told not to take too much water out as it would remove the 'good' bacteria.

 

[helterskelter]

Water change and treat as I've already stated.

Myxazin, melifix or salt (aquarium salts not table or rock salt)
Opaline Gouramis will tolerate a little salt but not for prolonged periods and some catfish will not tolerate any at all so u have to watch what fish u have.

Get some medicatio above and treat to stop this fungal infection ASAP

take the advice you have been given here and do the w/c etc,there is no beneficial bacteria in the water,its in the filter media where the bacteria grows.
waterchanges can only do good when you have ammonia/nitrites in there.

 

[hughessomefish]

yep couldn't agree with harlequins more good luck

 

[OldMan47]

The nitrites that your fish shop told you about means lots of large water changes. I would do a daily until I was able to measure the nitrites for myself. Water changes, meaning good clean water, are also one of the ingredients to a quick healing of the fish, especially if the damage you saw was due to a water quality issue.

Just wanted to update you guys.

The molly is doing great! He is alot more active and the growth has pretty much all gone.

Did the water changes & medications as suggested here.

Thank you all for your help!
