The worms I feed are just frozen. Not freeze-dried. I feed them Hikari Bio-Pure Frozen Blood Worms

Aquarium Fish Foods: Hikari Bio-Pure Frozen Blood Worms

The woman who I had gotten him from, fed him feeder fish and freeze dried shrimp I do believe. But he looks really healthy. And hes huge. And if the female is bigger than he is, lordy she gona be really huge lol!!! The only other ACF ive seen were little small ones. And I think hed try to eat them. They are barely 1/4 the size he is, and hes full grown... the first time i attempted earth worms, he didnt like it. but a few times after that, i guess he was so hungry, he ate it. But hopefully i will be able to get a 20g long here soon...

what type of filter would be best? one that hangs on the side(which he has now), or one that is submersible? or which would be cheapest?

I also use the TetraFauna AquaSafe Reptile & Amphibian Water Conditioner for their water... All of my frogs actually. They seem to do better and soak more often than with other conditioners ive tried...
