Hi,

I don´t think that your frog went blind; it´s more likely that he doesn´t feel well for another reason (which is yet to identify). However, amphibians in general spend much time doing nothing, so it´s possible that your frog also gets calmer because of its age (of course, he´s still very young, but he isn´t a "baby" anymore).

Freeze dried foods can cause constipation, which may lead to serious health problems in frogs as well as in fish. Also, they hardly contain any nutrients. Therefore, it would be great if you could get the frozen food and the worms.

Can you upload some pictures of the frog and your tank setup? Maybe anyone can notice something and give you further advice.
