I had thrown 3 zebra danio's in my outdoor pond in the spring. With the alge finally cleared I noticed at least 30 babies in the chilly water. I netted some out and put about 7 babies in my 150 gal and 9 in my 130 gal indoor pond. It's easy to see why they they have been so popular through the years. They never stop darting around and are colorful. If anyone on Long Island wants some catch em and their yours.
