I have a planted tank with 9 Panda Corydoras I purchased as juveniles last year that are now adults (and am lucky that one grew up to be of the long finned variety).
I had a bit of a pond snail explosion and have been paying extra close attention to the tank, trying to remove the pond snails (we are talking a serious issue, I have been removing 150+ by hand per day for weeks).
In the midst of snail picking, I saw something tiny flash across the bottom of the tank. I peered all around the edges of the tank with a flashlight and saw a weird little tan snake-like thing, maybe 6mm long. I suddenly realized OMG I have baby pandas!!! Carefully watching the tank for the next few days I saw at least 4 baby pandas, the smallest looking to be 7mm long and probably no more than a week or two old, looking more like a tiny little tan snake than a fish. However, one baby is substantially larger than the others and looks like a miniature cory, and just started hanging around in the open a little today (pictures below of him near one of the adults).
My concern is how do I keep these babies safe? I had added assassin snails to take out the pond snails and now I am worried about the baby pandas. I was going to try feeding less for a while but again, I don't want to put the babies at risk. I am amazed the cories spawned given I have pretty hard water and high pH. I had no intention of breeding, but am delighted about it, and really want to take proper care of these little guys.
Sorry, I couldn't get a photo of the tiny 6-7mm babies, but they are hiding in the dark where they are hard to see and I didn't want to stress them out with flashlights trying to photograph them.
