No itching, no discoloration, her blue eyes looked perfectly clear. Fluval 405, 40 gal, 1 clown, 1 lemon peel angel, 1 royal gramma, hemits, 1 feather duster & a rock of mushroom coral. She always eats whats down in the water, but last night I saw her eating some from the surface. I wonder.....I got up this a.m. expecting her to be dead but she's swimming around. Maybe she had gas? I will make sure none of the food sits on top. I sure hope thats all it was. Thank you so much.
