Fish in your Water Garden FAQ

Do I feed my fish? 

This will largely depend on what type of fish you have.  If you have larger fish like koi or tilapia, you will need to feed them at least once a week, depending on the environment and what the fish are accustomed to.  If they have been fed daily you will want to continue that feeding schedule and wean slightly (if possible), over time to cut down on the waste in your ecosystem.

Do I feed my platies, guppies or mosquito fish?

For small fish like platies, guppies, or mosquito fish, you will need to feed them a little if they are indoors. If your container is outside, you should never need to feed your fish.  Let the fish eat mosquitoes, mosquito larvae, water bugs, aphids, and algae.  Then you have a healthy mosquito trap that will cut down on mosquitoes in the area.

How to cut down on feeding?

If you have been feeding a lot, cut down gradually. This will make it easier to balance your ecosystem.

How much to feed koi?

Follow the three minute rule. If the food is eaten within three minutes it is a good amount for your koi. If there is still food floating on the water after three minutes, reduce slightly.  We have koi food available for sale in 1-2 pound bags.

Where have my fish gone?  

Look for a stalking cat or signs of a bird perching on your water container.  Dragonfly Larvae are famous for eating small fish.  Add more shade with surface plants, creating an ideal underwater ecosystem (the aim is for 60-70 percent water surface coverage).  Add three small fish, such as platies, and try again.  Sometimes a young water container garden has a hard time supporting many fish in the beginning. Start with three platies and see how it goes — odds are you will have a male and a female and they will breed based on how much natural food is available to support them in the balanced ecosystem. If you don’t see more fish within 30 days, you may need to add another fish or two.
