Something Wrong With A Blue Tetra.. And Now The Mollies

[Donuts]

Hi
Noticed yesterday that one of the normally active blue tetras has taken to swimming in one spot, and now it is quite near the bottom in the one spot. Its belly looks swollen, and it is a bit red around its backside.
Any ideas what could be wrong? All the other fish seem fine.

Can you post water stats in ammonia, nitrite, nitrate, and ph.
What do you feed your fish.
Are the scales sticking out.
When you say red around the back side to you mean the anus, with dropsy a fish can also get inflamed anus.
Look under dropsy.

Apologies... Here is the tank/water info:

nitrite: 0
nitrate: 5
kH: what is this?
gH: and this?
tank temp: 28 C

Fish Symptoms (include full description including lesion, color, location, fish behavior):
see post above; update: yesterday evening it was a lot more active, swimming around with the others, today it has gone back down to the bottom again and is swimming in the one spot. In addition it looks a little yellow/brown around the top if its head. Havent seen if it is eating or not.

Volume and Frequency of water changes:
10% water change every week

Food: flake food and the occasional pea, catfish pellets & pleco tablets (not all at once)

Chemical Additives or Media in your tank: none

Tank inhabitants: 3 black mollies, 5 glowlight tetras, 5 blue tetras, 5 neon tetras, 1 albino cory, 1 common pleco

Recent additions to your tank (living or decoration): 3 black mollies added 3 weeks ago.

Oh, and the scales dont appear to be sticking out.
The photo on the link posted of the fish with dropsy looks a bit like it. If it has dropsy, what do I do?!

Don't feed the fish for a few days if its still bloated.
Only peas which help with constipation get things moving.
The yellow brown on the head can be velvet to columnaris if its not the fish normal colouring.
Can you decribe the texture of the brown and yellow does it look like velvet or fluffy or cottony in appearance.
Shine a torch on the head with tank lights out to see if the yellow glows up.
Have you seen any fish acting strange like darting around, or flicking and rubbing.

 

[Donuts]

Thanks for the reply.
Ok - will try a pea diet for a couple of days.
The yellowy tinge is not on the skin as such so it doesnt have a texture- its more a slight colouring under the skin.
None of the other fish seem to be acting any differently to normal. One of the blue tetras is a bit of a "darter" and chases some of the others around sometimes, but he isnt doing it to the "sick" one at all. The others are just leaving him alone.
His stomach still looks bloated, and he is opening & closing his mouth more than the others.
Will keep an eye on him.

Get going with the peas.
Cook for a few minutes, let cool down, pop out of shell, mush between fingers and add to the tank.
Epson salts bath are good it helps draw the fluids out.

RIP poor fishy! He didnt make it!

Now one of the Black Mollies looks like he has small white bits of fluff on him, and one of the other Mollies looks like he has pop eye.

The fluff first appeared on the Molly the morning after we added a Pleco pellet for the first time the night before - could there be a connection? Then the "fluff" went away, and now it is back again. The others dont have any fluff.

Is there likely some fungus/bacteria going on in the tank do you recon?

[WILDER]

Get going with a bacterial med.
Where is the fluff on the fish.
R.I.P.

 

[Donuts]

It's all over really - small dots. But mostly on the body - not the fins, tail or head.
What kind of meds would we need to use?
Can we put it in the tank with all the other fishes, or do we need to just treat the fluffy fish?
Considering what happened to the blue tetra, perhaps they could all do with a dose of the bacterial meds!

[WILDER]

The small dots do they look like grains of salt.
Any signs of flicking and rubbing.

 

[WILDER]

Sure the dots are not whitespot as when whitespot left untreated the spots start to join up and look fluffy.
Whitespot looks like the fish has been sprinkled in salt.
Bacterial meds united states maracyn one and two.
Uk myxazin by waterlife or anti internal bacteria med by interpet, if a fish has columnaris best adding pimafix with are bacterial meds in the uk.

 

[Donuts]

I am not really sure if it could be whitespot or not. We are very new to the whole thing, so have had no experience of any fish diseases as yet! The dots are not joined up, but definitely raised, and fluffy looking like small balls.
I also just noticed some cotton like long bits of fluffy thread hanging off one of the plastic plants. Does this help with the diagnosis?!
Thank you for all your help

 

[WILDER]

ok I would add maracyn one and two.
Good luck.

 

[Donuts]

Is that the US name? We are in Ireland, so I would imagine that the meds would be the same as the UK?
Will pop down to PetWorld tomorrow!
Thanks again.
