Goldfish Fry Hasn't Become Free Swimming Yet And It Has Been 4 Days Already...

It's been 4 days now, since my goldfish fry (I only decided to keep two eggs) has hatched and they are still not free swimming yet and it's worrying me since i've read that they should be in 2 days... I have them temporarily in a small plastic box with some plants as they were not planned and were spawned out of nowhere. today is the 5th day and they're still on the floor/hanging onto the sides of that container. when the container is moved or they are lightly touched with a toothpick, the dart really fast around the container and then slowly float back down to the ground...so they seem healthy? I also can't tell if they have used up their yolk sacs yet- i'm new to keeping fry so i'd like to know if they're going to survive or not.

since it is a small container that they've been put in temporarily, there is no heater nor filters. (though the weather has become warm lately, so I hope it'd be alright.)

 

they are just hiding. have you crushed up some fish food for them to eat?

since you don't have a filter, do small water changes every 3-4 days.

good news today! they are all free swimming and are looking for food. I will definitely do water changes as you have said, thank you so much for the information!

just one question though, do you think it's a good idea to just use some of my fish tank water to change the fry's waters since the container is so small that I feel that the pH could easily spike it I accidentally put too much pH up when adjusting the pH levels? or should I manually change the water like I would normally do with my fish?

 

don't use tank water,since its been "used" and has waste in it.

mix a bucket of water, use what you need and either save for the next water change or top off your larger tanks.

ok!

I just got pond/tadpole snails today and I added 1 into the small container in the hopes that they eat up any leftover foods but my main concerns are that:
1) will it harm my fry?
2) will it slime up the water and make it hard for the fry to go up to the surface and breathe?
3) and lastly, will it do more dirtying than cleaning (like the amount of poop they excrete vs the amount of algae and food they actually eat)?
