Tips for Hatching Fish Eggs?

[Daydre]

I plan on buying medaka eggs directly from Japan to hatch out; as they're expensive (at least relative to my income) I'm a little nervous about hatching and raising them since this would be my first time hatching fish eggs. I've been able to gather the basics off of youtube videos; ex. keep the water clean (50% water changes every day until they're a certain size), feed fry a variety of foods more often than you would an adult fish (3-5x a day) bc they have small bellies and quick metabolisms, use one (1) drop of methylene blue per (variable) no. of gallons of water to keep the eggs from fuzzing up (and, failing that, use tannins from botanicals), etc. etc.

Is there anything I'm missing or have I mostly got everything down? Is taking my first try at hatching eggs with ones that are so expensive a bad idea? I plan to order them late March/early April to make sure shipping temps don't dip below freezing in my area, is this a sound idea? A little worried about temps in my house but I've heard medaka eggs just need to reach a certain number of degrees across multiple hours to hatch.

Apologies if this is in the wrong section, figured egg hatching was bundled into breeding.

Sounds like you have done your research, good for you. I believe you have it planned out well. They are an easy fish to hatch and raise.

I hatch Angel eggs and Cory eggs pretty often in little 2.5 gallon tanks. 2 gallons of water, 2 drops of methylene blue, and then I put an air stone under the Angel eggs to simulate the parents fanning them. 

 

Methylene blue helps keep any fungus spreading to viable eggs.

I’ve had mixed experiences. I think temperature with the eggs matters. I’ve bought from Japan in winter and had poorer hatches then I had with eggs from Hawaii in spring. Follow their directions and have all your foods and setup all ready before putting the order in. You can do a dry run with some killifish eggs if you want but I say once your got your setup do it.
