So I was feeding my tiger salamander today and I saw something reddish/ kind of orange round thing. It was hard like a pebble, I thought it was a pebble so I left it there. Then I saw this weird white string then when I looked closely it had leaves! I took it out and there was the same kind of pebble attached to it. It turned out they were seeds. Where did these come from? has this happened to anyone?
