So its been about 5 months for one of my frogs since metamorphosis. The other 4 months. Anyways, when they first became frogs, they were 1 1/2 inches. Now the younger one is just shy of 2 inches, and the older one is between 1 3/4 and 1 7/8 of an inch. The caresheet I got with them said between 1 and 3 years to mature. Now I understand bullfrogs can be as small as 3 1/2 inches, but how can I get them to grow to at least 5 inches? I know genetics and possibly even when they metamorphose impact size, but is there any way? Say maybe feed small frequent meals, instead of the twice a week feedings I give them, or increasing the water temperature. The temp in the water is about 24-25 degrees Celsius. Thanks.
