So I noticed Sami had this green stuff on her nose/beak tonight. I thought initially it was just lettuce but now I'm questioning this... I tried prodding it with a q-tip to try and get it off but that didn't work out. I let her soak for 30mins thinking it would definitely come off then but that was a no go too. Could this be some sort of infection? Nothing in her habitat had changed and she is indoors in her tank. Thanks.
