^^^ It's real difficult for them to get up on that floating plant...no toe-hold to push up.
I just returned from Walmart. Bought four orange fish to add to the other two. They are only about an inch long. 25 cents each! I don't think I've ever bought 4 items at Walmart for a buck!
I hope they don't get eaten by the larger fish.
