I am feeding 7 day old baby Oscar fry fresh hatched brine shrimp. While watching them feed I see several squirming things swimming among the fry. They are smaller, but at first glance look like very small fry. They are much bigger than the brine shrimp. I can see them a little better with a magnifying glass. After being removed from the tank they appear more “wormy” either dark green or black. I have tried to Google images but got no where. I yanked ‘em out and put ‘em in a jar with their own brine shrimp…thought maybe if they survive I could identify them better. Any ideas? parasite, larvae??? Wonder if I’m introducing them along with the brine shrimp or if they were there and I’m just now noticing…eeewww!
Well, I am kinda ruling out fish lice.Looked at a couple sites…not relating much. Much more wormy looking, and squiggles at the top of the water. These things are definitely visible but small enough to not get a lot of detail. I don’t see any legs but the body seems a bit like the dragonfly body…thing is I am in the middle of the suburbs no water sources other than my tank and spring hasn’t really hit here. hmmm. My adults seem perfectly healthy, no signs of any ailments. No problems until I put in the brine shrimp but may not have a thing to do with it. Just don’t want to have some nasty stuff in the tank.
Okay, maybe we’re on to something here. The Midge thing seems to fit. I am seeing a few of those flying insects…the larvae is about as long as they are!..So everything should be cool?http://www.naturegrid.org.uk/biodiversity/invert/midges.html
