I have newly become a fish mommy, I have raised the two legged kids and the four legged kids but never no legged kids. Recently bought a home with a Koi pond. There are four Koi 5 or six inches at least four frogs. I know absolutely nothing about this but am looking forward to learning. There is so much muck in this pond I'm afraid to clean to even pull out the dying lily for fear of choking the fish?? Before & Now pics - one month and plant was infested with aphids I think and just dissolving into the water??? So many questions not even sure where to start.
