I would believe it is mosquito. Because you have a large external filter does not mean you have a lot of flow. My 30g tank with a 900gph stream maker has a lot of flow, 30 turnovers per hour. My 75 SPS coral tank with 2,400GPH has 32 turnovers per hour. That's a lot of flow. As filters get dirty they slow down. Get yourself a powerhead and put it near the surface of the water. It will prevent it from happening again. As to your current problem I'd say guppies but your Oscar
should eat them in seconds. I have a small pond int eh yard that I keep guppies in to eat the mosquitos.
