A lady brought me a ton of pond plants last week, and she also brought me several mosquito fish. At least one of th fish has given birth since then, and two others are pregnant... one looks like she is going to pop any day now.
Here's what is interesting: my RES totally ignores them. They are a gray color, but they are sort of reflective. When they are in the pond, they look like little shadows. I can only see them if I lean close to the water and really look for them- and if I am looking into the depths, I might not see one that comes up to the surface.
When a goldfish or a rosie is added to his water, he goes nuts. He will spazz out chasing them. But he is basically ignoring these fish. I wonder if the drab coloration is part of it? Earthworms and snails are drab too, but he loves those and generally doesn't miss a chance to eat them.
I almost never actually see these fish visit the surface, so I don't know if they are actually eating mosquito larva. Maybe they are eating them all so fast that they don't need to hit the surface very often. I am sure there are plenty of bloodworms and insects in the pond for them to eat, so I don't think they will starve.
