sand for a fry tank?

[duendecillo]

I'm going to buy a new tank (about 60l-15g?) for my guppy and platy fry.
They are only a week or less old.
How do I set it up best?
Can I use white sand?
Best temperature,...........?

all advice is welcome!

My fry bowls are all different. Some have gravel, some have big river stones and some have a bare bottoms, but I don't think it makes a difference. But what they do have in common is they all have plants(mostly moss since its perfect for hiding and so they can snack on it). Plants make them feel secure b/c at that size they're all really nervous and scared and therefor want to feel protected.
Then they all get fed 3-4xday until they're one month old , then I reduce it to 2xday(what their parents recieve). Daily or every second day water changes are done to make sure there's no diseases present in the water and to get plenty of oxygen since most are in 1 gallon bowls that have no filter. Temperature ranges from 75-79 F. I haven't had any deaths out of over 200 fry so I must be doing something right.
