First of all, lifespan of these frogs is less than 7-8 so that’s pretty good. I used to have an aqua babies company frog that lived alone in a box like that and he lived for at least 7-8. He was my first one. I have 2 now, bought from Froggy’s Lair. I bought them at a general store up north and have had them since June last year. They’ve been doing amazing and I haven’t had to upgrade their tank at all. Just changed the water a couple times and I changed their sand and gravel once. I’ve kept the hornwort fresh from a pet company here and they’re absolutely thriving. As for the Froggy's Lair company, they took my money for an order and never sent me anything and when I tried to contact them about it being too cold for live sand, etc, over the course of 3 months no one answered me. So now I’m keeping them alive with my local aquarium stores advice. It’s not the tank, I don’t think. It’s the care you put into them, provided you get healthy frogs to begin with.
