Zerbra Danio fry!

As Newman says, its water that is green! Algae and other tasty critters suspended in it. Fairly easy to grow if you have a small container and sunlight available. I use a glass jar that is meant to brew 'sun tea' and then can use the pour spout to take out the amount I need without making a mess.

ok cool, give me a bit of a run down, I get an old jelly jar or equivelant, add tank water.. sit in the sun??

Hm, I should make this too.

I use a one-gallon jar, not sure how large the jelly jar you have is. I started it by adding some algae that I scraped off the wall of a friend's goldfish tank, and siphoned water off one of my planted tanks to fill it. I keep it inside on the sill of a window. It gets sun a few hours a day, but not all day (can overheat). Been going strong over a year. I top it off with water from one of my tanks when I do water changes.

Would brown algae work? That's all I have in my tank.
