Alex and Molly suggested getting a tank divider to keep the littles safe from Fluffy.
So I bought one at lunch and put it in tonight. It was about 1 inch too narrow, so I used a row of suction cups to hold a piece of tubing in place to plug the gap. Then I had the challenge of catching the littles and putting them in their side. Those guys are fast! I fed the two groups separately and all seems well.
Then I sat down to watch them, and what do i see? one of the littles has gotten through the gap and is swimming around the big half of the tank!! Silly fish!
While I was in there, I moved some of the ornaments around and planted the onion plant a bit deeper. I also took the strawberry basket out since the sword plant is now on the littles' side and they don't eat it. I hope it will now be able to grow big and strong.
The divided tank looks kind of strange, but it will keep the littles' safe. I wonder if some of the eggs will hatch now that the goldies aren't there to eat them?
Thanks for the suggestion, Alex and Molly.
