Outdoor Tub Pond with Mosquitofish (Gambusia affinis)

- I set up a tub with plants, amphipods, bladder snails, and Mosquitofish. I also added some large rocks to the bottom to host beneficial bacteria. There is no filter or air pump, the water movement seen in the video is from the fish feeding at the surface. The storage tub holds about 20 gallons and has nine fish. Occasionally I will throw in some fish flakes but 90% or more of their diet comes from what's living both in and on the water. Gambusia affinis are livebearers native to the US, but they have been introduced all over the world where they have outcompeted other species. A very controversial fish. Our County Health Department gives them to residents for free to control mosquitos in outdoor water features. In addition to mosquito larvae, these fish will eat their own fry, so I filled the tub with hornwort and java fern to give the babies some places to hide.
Here's a video that shows these fish and their interesting mating behavior:

Great video thank you, I was mainly concerned about not having a pump/filter, good to know they are okay without!
OMG! I was looking through youtube for Gambusia affinis videos and spot this one. Thinking to self "this looks like the ponds my friend built"
lol! Glad you found me.
We had a 2500 gallon put in a few years ago. We purchased a couple of Koi and 6 mosquito fish. I year or so later, there were probably hundreds of mosquito fish in my pond! A large contributor to the ammonia content… every so often we scoop them out and bring them to our river (allowed in Tn).
Yes, they are very invasive. We're lucky they are native here!
@@tomi.d Funny story… we moved to Florida a few months ago - the local county office is having a “free mosquito fish” day where we can go and get a bagful to put in the retaining ponds behind our homes to help with the mosquito situation.
@@ChristineMaentz Given your last experience I assume you passed them up, lol.
@@tomi.d Well, not in this case - this is a fairly large retaining pond (you see them everywhere in south Florida), there are plenty of mosquitoes here to feed the fish!
@@ChristineMaentz lol, good call.
This is awesome. What kind of bubbler do you use and how do you power it? I'd like to do this and I have a solar-powered battery outside I might be able to use. The mosquitoes here are insane.
I don't use any air at all in the tubs. These must be the hardiest fish on the planet as they are breeding in some pretty extreme conditions. A lot of pine needles fall into the tubs and I don't remove them all. The water level also drops drastically during droughts in the summer and gets well over 100 degrees F.
Can U post more videos of this pond please
Here you go, let me know if you have any questions.

Hey I’m doing the same thing, I have no water aerator tho, just an upside water gallon that slowly drips into the tub making bubbles. What ya think do I need an aerator
The fish will be fine without an aerator. You don't want the water moving or the mosquitos may choose another place to lay their eggs.
I don’t have my Gambusia Afinnis in a tote just yet. I got them from our front ditch. Mine are in a container with algae on sticks and some duckweed. The algae are for additional food while the duckweed provides some cover. I’m dipping mosquito larvae out of a place that has them and are feeding them to the Mosquitofish. The water is from rain I caught (it’s not illegal to catch it here).
In essence, I’m putting all of it to work as a nutrient source (no, I’m not killing any of the fish) for my potted fig trees.
I’ve got a few videos of this starting effort.
Wonderful! I'll check out your videos.
@@tomi.d, only a few of them are for the fish. Sorry.
Get confused
Thought that when water movés mosquitos don't go there
Yes, that's why I don't use pumps in the tubs. The only water movement is from the fish.
Today is Tubbs Tilghmag
Is true if Mosquito fish fast build the population?
Yes, they breed constantly, just like guppies.
Any chance you could aid me in finding out how to get them as well I’m in middle Tennessee about 3 hours from you
I got these from the Shelby County office for vector control, they give them out for free every year. They are under the Co. Health department.
What type of filter?
There is no filter or pump in the tub.
