I can't see why you want to remove the eggs. Remove the spawners. When I breed certain species of tetras I use a bare tank. The bottom of the tank has a plastic grate put in the fit the tank. The smaller the grate the better. This is used to prevent the adults from eating the eggs. After the fish have spawned, all you need to do is remove them. You should already have your infusoria cultures going by the time the spawners are finished. Other species of tetra's like neons, or cardinal I use spanish moss for a spawning medium. These species of tetra's usually start spawning early in the morning. I'll set my alarm so I'm up before it's light. And I'll watch them spawn. As soon as they're finished spawning. The adults are removed to another tank. I hope this helps you out.
