I am just speaking to my partner and the least active Platy is dead :'(
I was wondering whether it was ill from begining on, as it kept hiding and spending time on its own. She was difficult to get up to feed as well, but when she came up she did eat.

I will get a photo to see if the fish looks ill, but I recall her being strange.

There is another one (female) that is really big and she keeps getting big. Do you think she might be pregnant?

Water:
pH: 6.8
Ammonia: 0
Nitrite: 0
Nitrate: between 5 and 10

Waterchange was done yesterday with RO water

Aww sorry Sofia. These things do happen, especially with the mass-produced stuff like platies. Let's hope the other ones are ok. If you can get your other (better? /tongue.gif" style="vertical-align:middle" emoid=":p" border="0" alt="tongue.gif" /> ) half to photograph your fatty platy we'll be able to tell you if it's gravid (not pregnant).

How long did you have that Platy for Sofia?

As Matt says, this kind of problem is often seen with mass produced fishes. When I first started keeping fish, I purchased 5 beautifully coloured Guppies.. and they were all dead in the bag by the time I got back home, less than 15minutes away.

I had overseen the catching of them and they didn't look particularly stressed. They were in two brown bags and then kept safe in a polystyrene box.. yet they all died.

I had purchased 5 or 6 Platties and Mollies too which were absolutely fine, so I have to put it down to that shipment of Guppies being a fairly weak strain. Doesn't make it any less upsetting though! /sad.gif" style="vertical-align:middle" emoid=":(" border="0" alt="sad.gif" />

Oh, that is bad!
Thank God that didn't happen to me.

I had them 11 days now /sad.gif" style="vertical-align:middle" emoid=":(" border="0" alt="sad.gif" />

Partner is currently trying to get a good shot of the 'pregnant' Platy.

the male is very actively chasing her and she keeps trying to get away.
Aparently they are all not that active atm (only the Platies). Maybe they know one is gone?

Right, I have got photos.
Not sure if I should have posted the one of the dead one. To me it doesn't look starved or sick /sad.gif" style="vertical-align:middle" emoid=":(" border="0" alt="sad.gif" />
I am happy to remove it if the picture is not good /sad.gif" style="vertical-align:middle" emoid=":(" border="0" alt="sad.gif" />

The 'pregnant' platy is below. Please don't tell me she is ill and going to die. She was only half as big when I got her 11 days ago.

Hi Sofia. The thing that worries me about that is that I can't see a "gravid spot" on that fish. When livebearers are gravid you can almost always see the developing young as a dark patch near the anal fin/vent of the fish. I can't see any evidence of that on your platy. It does look rather unnaturally swollen too. That's not to say it's definitely ill, it's just difficult to assess from those pics. That fish could just as easily drop a load of fry in the next few days than be infected with something. Can you get a closer shot of, well, it's arse? Keith is our resident livebearer guru so maybe he'll offer some additional thoughts.

The dead one doesn't show any sign of disease I agree. You are remineralising your ro a bit aren't you?

Hi Matt,

Michael will see if he can get a closer up. For the meantime here is a picture of the other side of the fish.

Do you think she has to die? Michael doesn't think the 'bulge' is far enough back to be fry /sad.gif" style="vertical-align:middle" emoid=":(" border="0" alt="sad.gif" />
I think however, that in the first photo it looks as if there are many red dots towards the anal fin.

I hope she won't die.

They seem more active now again as well

We have not been remineralising. How can I do it and could that be the reason for her death?

All you need to do to remineralise is add some tap water. I would suggest immediately replacing 25% of the tank's water with tap water.

As a first step, I'd do what Dunc said too.

sorry about the platy, but i agree, many shop bought fish don't have the ability to fight diseases like those home bred.
as for the platy in the picture, it is hard to say. although there is no gravid spot, she is a gold/yellow platy, so may well be producing gold fry, therefor no gravid spot as we usually see.
best way is to have a close look at the gravid area, see if u can see any tiny black dots, any at all, if so then that is probably the fry, if not, then it could be she is filling up with fluid.
another thing you can do is look at her from the top, see if the scales are starting to protrude away from the body, what is called 'pine coning'. this is a sure sign of dropsy, and little can be done. this is the worst scenario, so fingers crossed she is gravid.
hope this helps, albeit a bit depressing in parts.

Ok, I tried to get a shot in focus of her back, but to no avail. I don't see what you described above. I am really concerned. I don't see any fry in the tank or still the fish.
The other female is swelling up now as well. I am really concerned!

Is there any other way to remineralise the water? I did the water change, but I would rather not pollute the tank with my tap water in future.

Any help is grately appreciated

You can buy products that do the same thing, but mixing in a little tapwater is usually sufficient and won't "pollute" your tank. Your platies and guppies will almost certainly fare better in tap than pure ro; I suspect it's the low mineral content that's affecting them. I'd try a 50% water change using tap water and hope for the best. Fingers crossed for you Sofia.

most livebearers do prefer hard water, ph over 7 and quite hard. so keeping them in RO will not be good for them. all my livebearers are kept in tap water, nothing else (apart from tap water conditioner). i have hundreds and all do very well. my ph is 7.5 and hardness is off the scale.
i would do some small water changes with tap water, see if this helps with the fish. if they are eating and swimming normal. perhaps all is ok. fingers crossed.

Ok, i inspected the biggest female closely from the side. It looks as if she has 'eggs' in her just after the silver looking bit.
Would fry look like eggs? I can't see any black spots like eyes or so /sad.gif" style="vertical-align:middle" emoid=":(" border="0" alt="sad.gif" />

How long is the gestation period btw?

Thanks

EDIT: I did another 10% water change today.
They are all lively, the male is still chasing the females around and they are all feeding well.
She looks very similar to this one http://www.canadianaquariumcon.....s/pp10.jpg

Wow that is one rotund platy! Sofia I'd tend to follow Keith's advice rather than mine where livebearers are concerned; he has much more experience with them than me. Try doing daily 10% water changes for the next few days and hopefully you'll see an improvement /wink.gif" style="vertical-align:middle" emoid=";)" border="0" alt="wink.gif" /> The other possibility of course is that your females are heavily gravid and we'll be seeing loads of babies soon...

that is one huge platy. there could well be eggs if she is not quite ready to drop the fry just yet. try and get the ph up to above 7 and hardness above 15ppm, higher if u can as they will benefit from this.

pH is around 7.6 now. If I do more water changes this will rocket though I think.

Will test for ppm this evening.
pH was never below 7.

Thanks Keith /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

P.S. The other Platy has egg like things in her too /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" />

Just a quick update. As I fed them this morning I watched the 2 female platies closely and one of them, the bigger one, has got a few tiny black dots in her belly /smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" /> They are inside the eggs, but not all have them...

I had them now for about 3.5 weeks and I expect to see some fry anytime soon really. How small would they be? I don't want to miss them and accidentally hoover them up!

Hehe and are you happy about it Sofia? The fry should be clearly visible and about 2-3mm long. Look around the substrate, at the surface and among the plants. They won't have much colour but their eyes will be obvious /wink.gif" style="vertical-align:middle" emoid=";)" border="0" alt="wink.gif" />
