I have a 160 gallon stock tank outside which holds 5 feeder goldfish.  They are getting larger every month.  I bought them about 6 months ago, and they have grown about 4 more inches in length, and at least an inch in width.  As with all of my tanks, I have no filters, just air lines with bubblers or airstones.  Plants do the filtering.  I have water lettuce and duckweed floating on top of the water.  When I first put the fish in the tank with they were very small (17 cents ea. feeder goldfish), and I never saw them eating the duckweed.  But as they have grown, I see them munch on the duckweed upon occasion.

So far, I am able to keep at least half of the surface covered in duckweed and some small water lettuce (no direct sunlight on tank so plants don’t grow very large).  The duckweed supplements the cheap pellet food I give them.  Their colors are vibrant and the fish are growing very well with the cheap pellet food and duckweed.  But I would like to give them table scraps too.  I often have leftover rice and vegetables that are cooked and plain (no oils, etc.).  So I found a list of foods that will help supplement their diet of duckweed and pellets.  Credit:  http://goldfish2care4.com/goldfish-feeding.html

‘Tips for a healthy goldfish diet:

  • Feed your goldfish once a day. Don’t worry about starving your fish. All he needs is what it can eat in 2 minutes
  • Feed your goldfish fruit and veggies regularly (every 2 days)
  • Make sure that all hard vegetables like carrots, beans, rice are cooked, pealed and finely chopped up
  • Goldfish have their favorites just like you do, so keep a note of what foods they enjoy
  • Feed larvae, shrimp or daphnia only as occasional treats, they are protein rich and can cause constipation
  • Keep an eye on your goldfish and notice how healthy they are. If they are floating at the top of the tank, you need to take steps and deal with the Swimbladder
  • If your goldfish is gasping at the top of the tank for too much time this doesn’t mean it’s asking for food. Healthy fish spend little or no time at the surface. Your goldfish may not have enough oxygen
