Unexpected Zebra danio fry

[Rii]

Is this a zebra danio fry? Tiny thing in the upper right region (sorry for terrible pic) it looks transparent from bottom and side.

If it is a fry then what should I feed it? I heard egg yolks but how should I prepare them and how much and how many times? (I can't really feed it stuff like brine, daphnia etc cause i am from a tiny city which doesn't really have anything) this is the only one I found. It seems my 7 danios probably had a fry party.

What other things should I know to care for it? Temperature, water change etc anything that I might need to know.

And sorry for asking so many questions I panicked when I noticed this guy (I had no plans for fry I only bought my danios 4 months ago. But I really want to )and ended up making an account just for this. If I fail to reply (social anxiety suddenly hitting me like a ton of bricks lol) please know I am REALLY grateful for any and all help!

About half way down the page in the following link is information about making boiled egg yolk for fish fry.

Back to Basics when Breeding Fish

STARTING OUT Make sure you have a pair, (1 male + 1 female). There is nothing worse than spending your hard-earned dollars buying a couple of fish to try and breed and ending up with a pair of fish of the same sex. Let's face it, to reproduce fish you need a male and a female. Two males won't do...

You keep the water the same temperature as the adult tank.
Have an airstone very gently bubbling away in the container.
If possible have an air operated sponge filter in the rearing tank.

If you don't have an established biological filter in the rearing tank, you will need to change most of the water each day to keep the ammonia level down. You can refill the rearing container with water from the parent's tank.

Add some live plants to the rearing tank and they will help keep the water cleaner and there will be infusoria (in small amounts) on the plants that the baby fish can eat.

Don't use a net to catch the baby fish. Use a plastic container to scoop it up in some water.

Thanks for the early reply. I will try feeding him with this.

I have already seprated him from his parents in a tiny fish bowl with some frogbit.

I have a question about temperature tho. You see it's winter at my place and my danios live in a 15 gallon kid's pool kept in semi shade with a lot of plants (crypt, java fern, frogbit, lotus, bacopa,ludwiga etc) no equipment. Adding aqaurium salt once a month and 30% water change once two month or so (I did a water change five days ago) (The parameters are stable and they all look active and healthy hence the fry). But the temperature sometimes drops to 16°C on colder nights (average temp is 20.2°) . I am worried it might be too cold for him so I was thinking about a heater.

Basically I plan on putting him in a fish bowl with water from my outdoor mini pond (where his parents are) and put some frogbit and and java fern in it. Put an air stone (I will buy it today) and a heater. But can you tell me what temperature I should keep it at? I have no idea.

Ideally you want the temperature over 22C (between 22-26C), however, if the fish was born in cool water and it is only a day or so old, it will be fine in 20C water.

--------------------

Why are you adding salt to the pond?
Salt (sodium chloride) should only be used to treat freshwater fish for diseases that respond to salt. They shouldn't have salt in the water all the time because it can damage their kidneys and shorten their lives.

Thanks for the reply.
I will try keeping the temperature at 20 then.

As for the aquarium salt. The lfs store I bought my fish from suggested putting it in to prevent parasites or something. I guess I will stop putting it in. Tbh as I was already putting way less than the amount he recommended, I doubt it did anything in the first place so discontinuing it will probably not change anything. (But my money will be saved which is good)

 ------------------

By the way I read the post. It's very informative esp for newbies like me so Thanks for writing it! It helped me quite a bit like green water , I gave the lil guy some green water I had in a bucket outside. (I keep it so mosquitoes can lay eggs in it and I can feed their larvae and occassional blood worms to my fish)

If you use salt to treat parasites you normally do it for 2 weeks and then stop. You don't need to keep adding it and the fish will be fine when you dilute it out.

If you have a container of green water, that will make a great food for the baby fish. You want the water that the fish is in to be green not clear. In a couple of weeks you can start to crumble up fish flakes into a powder and offer a very small amount of that once or twice a day but get it through the next 2 weeks before doing that.

Ok. I will keep this in mind. Well then I will put him in the green water.

Let's see how it goes. Hopefully he will survive. Thanks for all the help.

Don't put it in with mozzie larvae or they will eat him. Move some green water into the fry's container.

Ofc , I won't put him with those guys lol.

I actually took green water from there and put it in his bowl. He seems to be doing fine for now.
