Probally so. They breed really easy. The platy will get pretty plump & they'll have a dark gravid spot by their anal fin. When she's ready to give birth her belly will be quite boxxy shaped check out the profiles I'll get a link in a second I had written one on platies and also search on google and you'll be able to find tons of info on 'em.
Yeah if shes clear you should be able to see her gravid spot well...she should have little black dots behind her belly...eyes...also she may act a little different instead of swimming with others she may stay down beside some plants.
Ok here's the easiest thing. Go to a petstore and get a breeding trap only cost like not even $5.00. I would get the one with a V-shape seperator. Put the platy in here, they stay pregnant from 20-40 days usually 28. So when her stomach gets boxy put her in their. Once she releases the babies immediately remove her from the trap along with the seperator. You won't need to feed the babies for 24hours. You can buy a product called Liquifry or Wardley Small Fry which are liquid foods or Hikari Fist Bites which is a powder. What I do for my livebearers is feed them Wardley small fry for the first week then crush up flakes in a baggie and feed them to babies
It depends on how big & how old & 1st batch or whatnot. If it is its first birth probally not over 20. They are easy to care for. Once they get bigger I'm sure there is a LFS 'round you that would take them. They wouldn't give you money probally not even storecredit but if you enjoyed raising them it wont really matter to give 'em away for free.
I got a penn plax 4-way breeder tank and hikari first bites. Are the babies small enough to fit through the small slits on the bottom? And can someone find a pic of a platy ready to give birth for me please??? thanks!!!
20 gallon tank
7 Platy Fry
2 Head and Back Light Tetras
2 Fancy Guppies
4 Neon Tetras
You know quite possibly she will eat the fry. So if you just want to keep a couple of them just leave her in your big tank with the other fish and keep a couple of them in the breeder net till they are big enough not to get eaten. Keep watching her. After this batch of fry she will have another batch in a few months, then another lol.
