Welcome bittyme, nice to have you on the forum . Greens are so cute .

Autumn has given you some good advice.

Perhaps a nice large tank would work well for you and your frog. They love nice large vining plants such as the pothos .

A good trick for feeding is to us a smooth-edged glass bowl of 1 1/2" or taller and feed from the bowl. He will learn the bowl is where the food is. You can count the crickets and you'll know how many he eats. Offer food daily. His food should be no larger than the distance between his eyes for easy swallowing and to prevent constipation and impaction.

The calcium with vita D 3 is necessary for their health, along with the multivitamin. Many new frog parents are not aware of this. Their food insects should be lightly dusted with calcium every other day and the mvi one day a week, but not on the same day as the calcium. This will help keep them healthy and can prevent MBD (Metabolic Bone Disease), a disabling disease in which they lose mobility and jaw function, and more. Some good brands are Repashy, Repcal calcium with vitamin D3, Herptivite.

Spring water or dechlorinated tap water can be used for your little guy. All water should be chlorine and chloramine free and should be treated for heavy metals. All 3 are toxic to amphibians and will build in their systems with exposure. Dechlorinating drops can be purchased in the aquarium section or reptile/amphibian section of a pet store. Change his water daily. Also mist his tank 2x/day to provide some humidity. This keeps them nicely hydrated and helps them to shed easily.

Just a few tips for you .

Again, welcome. We look forward to hearing more about your cute little fella .
