would the fish be fine with the gouramI and 11 neon tetras? I'm also concerned that my filter could suck it upDemeter said:I doubt that is a gouramI fry. I'd need a close up picture but it is more likely to be a livebearer like a platy of guppy. If you want to raise it then separate it from fish big enough to eat it. A breeder basket would be very useful right now. If you can't get one just yet then float a container of water in the tank to keep it warm, feed finely crushed flakes for now and change the water in the container daily by poor a bit out and adding more back in from the main tank.
