Frogspawn causing trouble??

I recently added a small 2 head Frogspawn to my 10g (14g if you include the sump). Two days later my leather coral and GSP seem unhappy and withdrawn. The leather is pulled up tight... I added carbon yesterday to see if it's chem-warfare but no improvement. Could the frogspawn be causing issues? If so I can remove it and place it in my 125g which already contains a frogspawn... Any suggestions?
