Question

RCS-safe fish that eats mosquito larva for an outside container pond?


Thinking about doing a small 20-30g balcony container-pond to house/breed RCS, but I don't want it to become an insect cesspool.

Can anyone recommend some small relatively-RCS-safe fish that will eat the surface larva/insects without depleting the shrimp population too much?

Planning to heavily plant with hornwort, water hyacinth, and misc. clippings I have in my tanks. Plant-filtered only. Can't wire electricity to outside. Also have white fly, aphids, other insects, not sure what lays eggs in water.

Mosquito fish? May eat the baby shrimp but if there is lots of fly larva in the pond, they may leave the cherry babies alone.

Mosquito netting over the container? I keep a 10 gal on my back porch to cultivalte green water in the summer and I just put a mosquito screen over it. The water temps in small outside containers gets very hot in places like FL or GA.

Excellent suggestion. I like the beta idea. One beta can only eat so much and they are not know for being fast swimmers, so the shrimp should be ok.

Guppy. The original mosquito pro. Guppies will eat baby shrimp, but male fancies are slow and can't focus long enough to actually hunt for them. They also tend to hang out at the surface.

Male guppies work very well. Thats what I did in my outside pond for RCS. They usually always stay at the top and like they said they don't have a very long attention span.

Hmmm.... I'm curious- would mosquito dunks be harmful to shrimp? They contain Bacillus thuringiensis israelensis as a larvicide.

Least Killi aka Dwarf Livebearer would be excellent in those circumstances. And less aggressive than Mosquitofish.

And they are free where you live.

Hatchetfish? Halfbeaks? Neither go below three inches in the water column.

If you plant it heavily, especially with mosses and java ferns, your shrimp babies will have plenty of protection. Some of them may get eaten, but the population should continue to thrive.

My Betta gets my Cull shrimp.

I live the guppy idea. You still will need lots of cover for there shrimp, like a large portion of moss.
