So people use these isopods to clean there tanks correct? Also if a frog were to eat one is it safe for the frog? Is there certain species that are better other species to have? Wild caught Isopods (rollie pollies is what I'm use to calling them), is it okay to put inside tanks as long as you know it didn't live in pesticides or herbicides? and does the size of the isopod matter? I'm new to these cleaning bugs and I wanna make sure my information is correct! If anyone could get back to me I would greatly appreciate it! Any other comments and concerns are welcomed too!

Thanks,
Greg =)
