So iv got platy fry now. Mother and other fish grabbed the majority of them but one has survived a few weeks swimming around in the plants hidden away (even from my plecos) he's about 1/8 inch in size and iv netted it today and put it in a fry keeper box inside the main tank. He's a sole survivor as far as I can see (unless any more pop out).. Now I'm due on holiday in two weeks but I want to see if I can get it to survive but I don't want to release him back out and let nature take its course. Best way of keeping it alive whilst I'm away for 8 days?
