Benigoi or Higoi are Koi that are solid red. When buying a Benigoi, look for solid Hi. Check the fish over for any old scars or bad scales, for these will take away from the look of the Koi.
For many of us, our ponds are beginning to warm (or will soon be). Water temperature, not the ambient air temperature, is the gauge for what to do and when to do it in regards to your pond. Water temperature should be checked at approximately 1 foot of depth. Avoid feeding your fish until the water temperature is consistently above 50 degrees Fahrenheit. This will also be the time to start adding spring maintenance bacteria and enzyme treatments.
