This gravel is about pea sized. I imagine when they get really big they could pass it. I am worried about while they are growing... I just feel like I am flirting with disaster leaving it in there...
Thanks,
Carole
The gravel in mine is much smaller then pea size it's maybe like 1/5 of a pea, maybe you can change your substrate to smaller gravel it poses less risk then pea sized.
