Indiana Perennial Garden and Fish Pond

I'm sure you've heard that parts of Southern Indiana has been flooding and areas are still flooded.  We live in that area of Indiana.  The extra precip made my garden grow quickly and it looks nice and fresh at the moment.  Our pond fish have emerged with babies and are wanting to be fed often.  Most of the babies are still blackish green colored camo and haven't turned golden yet.  When they get a little bigger and can defend themselves they will be orange and grow fancy tails like the others.  We awoke this morning with two of our fish dying - something (critter) must have gotten into the pond and shook them up.  I tried to survive them (fish CPR) but it didn't work and we lost them to fishy heaven.
