Fry Development Photos

@patchincurtis That's a neat idea! We'll give that a try. Our home temperature, above ground where this rig is located, ranges between 71-75 degrees Fahrenheit during the summer. The 10-Gal tank is set for about 78 degrees. With the fry tank set up on the opposite end of the tank from the heater, it surely is a cooler temperature. Let me ask you a question: when you've observed your fish in a larger sized tank without a heater for a period of time, did you notice any tendency of the fish to drift up towards the water surface? Just wondering if there's a temperature difference in the water between the top and bottom of the aquarium that fish may make adjustments on account of in cooler conditions than normal.
