Nice. That’s always the most fun stage. As they grow bigger you may notice the numbers slowly diminish. The parents usually eat the weak or sick before they have a chance to get too big. Not to mention the occasional snack lol.
If you want them to grow up make sure you do wc often. The fry will be releasing pheromones that will later shape who is who in pecking order. Some will be almost doubling in size almost over night and others will take months to get to the same size.
Great updates. Thanks for posting
