Took my [3 y/o] son to Petsmart today because our 75 gallon finished cycling this past week. He picked out some Red Eye Tetras as his favorite. We got 10 of them and brought them home tonight. Did a drip acclimation and dropped them in the tank about an hour or so later. Flipped on the lights to snap a quick picture. As they sit they are about 1-1.5". Looks to be a mix of males & females based on size and shape. They are swimming around happily from what I can tell.
