i noticed a little while back that my frogspawn had a bubble form on it, anyone know what it is or what causes it, and what this fluorescent yellow sponge like stuff is

I had one that would do that from time to time. I really never could figure out what caused it but it didnt seem to cause any problems.

Thats the heads splitting. Its air caught under the skin when the coral inflates.

Its absolutely normal. Mine does it when it is preparing to SPL IT.
