(another) Poorly Platy

Hi folks
Just wondering if anyone has any advice about my poor platy, Mickey.
She has suddenly gone very skinny and seems to be really working hard to stay afloat. As soon as she slows down she starts to sink to the bottom. She has started to hide away in the plants, and only really comes out to feed. She always makes a big effort to get to the surface for food, though and seems very hungry.
I have started treating the tank with melafix but not sure if this is a good idea or not. I don't think she's old - I've only had her for about 3 months. Water tests coming back OK and all other fish seem fine so far.

I thought about taking her out and feeding her separately, but I think that would stress her even more - she's always been more sensitive than the other platies. Can't see any sign of worms, and she seems to be pooing!

Any thoughts would be welcome! Thanks

Aaagh!.....'Poo Watch' is back

Hi Lou

I suppose I shouldn't really moan about 'poo threads', as I have got a brilliant book all about poo, pellets and pee! It shows you different tracks and all sorts made by different animals. I got it to find out what was going through our garden...it's really fascinating

This morning I found some boar poo in the garden, presumably from the one that came tearing down our drive a couple of nights ago. He ran across in front of our friends car when they visited last week and I guess he's probably part of the family group that we have seen now and then.

I  have to say though, on the subject of boar poo,  that it's a whole lot bigger than platy poo....you wouldn't want it in your tank

Females don't usually fight each other, though there is always the possibility of a rogue fish.
However, healthy fish will pick on a sick fish, especially shoaling fish (though platies aren't shoaling fish). Sick fish are more easily picked off and attract predators. The other fish don't want to attract the attentions of a predator so will kill a sick member of the shoal so a predator doesn't see it.


If the fish is not eating, that would account for the skinniness; but if she is eating and is still skinny it suggests internal parasites.

Amazingly Mickey is still alive! I treated the tank with Melafix for a few days so I don't know if that made any difference. She is still skinny and shy but seems to be spending less time at the bottom of the tank and Minnie is leaving her alone too. So we will see...
