Moving fry

[Robbos]

My 64 litre tank is full of fry of varying sizes as I moved the female into a separate tank and she continued to deliver two more batches. I feel I need to move some out as the size difference is noticeable and the larger ones seem to vacuum up the food while the smaller ones stay near the bottom. The local aquarium shop has agreed to take them but not sure I can separate the sizes. Shall I move them anyway as the tank is appearing crowded?

Perhaps when the bigger ones are all up at the top sucking up the food take a big net to scoop them up. Take them out of there.

Free up the space as you already found there will be a bunch more. Keep up on water changes as those little guys really can foul up the water with feedings and just there are so many.

Your tank 64 liter is appx. 16G, not very big for tons of fry.
