Hello I recently purchased a trio of mint terribilis from the NARBC this past october. They are kept in a 12x12x18 zoo med that I made to have 2 levels and a water fall feature. The frogs were about 2-3 months old when I got them. I have had them for a month. One frog is growing normally, about triple the size of the smallest and double of the other one. The smaller 2 don't seem to be keeping up very well. About a week ago while I was misting the smallest went into a convulsion with its back legs and spread out and just about did the same to me when I saw it because I thought I had killed it. I left it alone and it eventually came back around but today it did it again. I have tried calcium and vitamin supplementation but he always seems to spit out the dusted flies. Any ideas how to help out? I would really be bummed if I lost him. Any advice would be greatly appreciated.
