Glad your frogs are doing well.This is one reason why this forum is so great, so many members offering accurate advice. Thanks to all who helped out!!!!
Like reptiles, amphibians are also prone to metabolic bone disease (osteodystrophy) which is basically an imbalance of calcium, phosphorus and Vita A/D3 in the diet. MBD affects clawed frogs, Axolotls and other large amphibians like bullfrogs, horned frogs and White's treefrogs. It is difficult to determine if the symptoms are related to MBD. Some signs include: splayed legs, open mouth, bone deformities, listlessness, skeletal fractures, prolapse, water holding, cramps and spasms.
Simply put, MBD is caused by improper or inadequate diet. Amphibians need to have a diet rich in calcium but low in phosphorus. Ideally, the Ca:Po ratio should be 1:1 to 2:1. A diet too rich in phosphorus will prevent the calcium from absorbing into the body. I noticed that ReptoMin has a Ca:Po ratio of 2:1.8. I have been using ReptoMin for years without any adverse affects on the frogs (personal opinion).
A deficiency in Vita D3 prevents calcium from being absorbed in the small intestine. Make sure the Vitamin supplement you are using to dust or gut load the food has Vita D3, not just Vita D.
An excess in Vita A causes a biochemical reaction with the Vita D and the calcium regulating hormones. Dr. Kevin Wright, in his book, Amphibian Medicine and Captive Husbandry, noted that one of the first documented cases of MBD in clawed frogs was in connection with an excess of Vitamin A in the diet. I understand that a product called Herpetal Amphib (Herpetal - Produkte für Reptilien und Amphibien) is a dietary supplement that works very well, but not sure if it's available in the U.S.
Adequate full-spectrum lighting may also help your frogs stay healthy. Some species like to bask in the rays
I hope this helps you prepare a healthy diet for your frogs. Good luck!
