The gold ones with the black spots are a month old. There were gold ones and gray ones at first. Mostly gray with maybe 3 gold ones. Now they are all gold with spots except for maybe 2 or 3 grayish ones with black spots.
The black fry are about 2 weeks old.
The gold ones I was catching for days as they were born. I didn't see them being born or know any fish was pregnant. I found a fry on accident and ended up catching 17 of them. I lost a couple. I think 4.
A couple weeks later, I was cleaning the tank and I moved some things around and fry came swimming out and into the corner of my tank. Little black ones. I had no idea! Surprise, again! I caught 5 of them. I missed at least 1. I don't know how many more are hiding in the main tank if any any more. I never see them. I didn't even know these guys were in there. The golden batch were swimming around and I would catch them. These black little guys were good hiders. They never came out, ever. I didn't know they were there.
