sick guppies

Good day

I have lost 7 guppies in two days. I have noticed that the ones that died was swimming in the stream by the outlet of the filter.
They also had this slimy whitish coating on their skin that also covered their eyes and head.
I did test the water and everything in the water seems fine.
What can it be?

Thanks.

 

What is your water temp
Have you added any new fish plants recently ?
Oxygen ?

 

@Corne. Yes plants and fish.
Water temp is 25deg

 

Dude, I'm going to stick my neck out on this.

Madmike, the Vicepresident of the Boston Guppy club has this to say:

SLIME DISEASE

What is it?
Also refer to Costia, as the two diseases share similar symptoms.

Not one particular disease, but more a symptom of various diseases.

It is very dangerous for a fish to overproduce mucus. If the mucus covers the gills death will occur rapidly from suffocation.

This disease will usually only occur when the fish are stressed. Common stresses include overcrowding, poor water quality, malnutrition or sudden temperature changes.

Symptoms:
Excess mucus covering any part of the body. The mucus is gray/white to blue in colour. If mucus is covering gills the fish will exhibit rapid breathing. The may also scratch against aquarium objects, however this may or may not occur. It is also indicative of many other parasitic fish diseases. Scales may be lost due to scratching.

Cure:
Firstly, make sure the water is of a high quality, check pH and ammonia levels. Do a 30-50% water change. Correct these and proceed with treatment.

General parasite treatments will work fine here. Copper based treatments, such as malachite green, work very well. These treatments may need to be repeated to ensure a full recovery. Remember to remove any activated carbon form your filter first, this takes medicine out of the water.

Salt added to the aquarium will make a great improvement. (0.6%) That's providing the fish can handle small amounts of salt.

Raising the water temperature slightly may also help.

 

@HeinrichvH sorry to hear about you lost I just had the same problem (dead guppies) but no white stuff covered
but I feel you sadness.

 

Yeah @BBQ. I can't stand it when my fish dies

 

Yup cos they are so cute + gets the wife on ur head in my case..

 

Lol. Same here. And I realy lost some nice males and huge females

 

I have show guppies(PETSTOP,s) and 2 females is very pregnant ,I will donate a few fry to you
God willing the fry make it

 

Hi Heinrich,

Although one commonly thinks that guppies are about the toughest things out, this is not quite the case. They are quite prone to the introduction of new fishes and then the slime disease as described by Henk, is one of the primary causes of problems. The bottom line is that in spite of all that one would think, even with guppies you have to quarantine new fishes before introducing them to a new tank. Fortunately guppies are not too expensive and can be replaced, although I can understand that you were proud of your own fishes and were attached to them

Kind regards,

Dirk

 

@BBQ - Have yours stopped dying yet?

 

I found one more dead guppy this morning. The rest of them looks fine. Will keep an eye on them during the day.

 

@Spath ye stopped but platy gonna go soon

I spoke to didi at petstop again today,
And I'm gonna take them there to see wtf
Is going on. Maybe do it tomorrow

 

Sounds like a guppedemic...

Sorry, that may be in poor taste.

 

Just did a 15L water change.
Took out one toy in there and replaced with 3 smaller drift wood that I have soaked for 2 weeks.
hopefully non dies from now on.
still wanna take those platys in and see whats going on.. or fish biltong will become of them.
I know it sounds shitty but gota let them go if they gonna cause more problems.

 

Found another dead guppy tonight. Man this sucks

 

sad man

 

@HeinrichvH how do the peform in ur current tank? floating or sinking, and is there any white spots or deform?
and when was last that you brought new fish / plants in the tank?
maybe something is dodgy - and what food are u feeding them?
