Inbred tadpoles?

[Geoff]

As some of you may know, I have 7 ACF. All of my tadpoles came from Insect Lore. Is it safe to assume that they are all siblings?

It's probable but only Insect Lore's supplier can answer that question accurately.

They won’t be sexually mature for another 6 or 7 months, but what happens then? How often do females lay eggs? I want to leave the males and females in the same tank, but what happens if fertilized eggs appear? What do you do? What happens if inbred tadpoles are raised?

The likelihood is that if you have males and females they'll produce eggs as soon as they reach sexual maturity. What happens then is up to you but if you're not interested in raising tadpoles just leave the eggs in the tank and the parents will soon eat them or any tadpoles that develop. I can't say with certainty what the long-term consequences of inbred tadpoles will be but it's not usually a significant problem for hobbyists like us.
