I have had this Goldfish
named Bowie for a few weeks after falling in love with his coloring. Tonight I noticed he can't close his mouth. I gently netted him and inspected him by hand for a few seconds and could not see any gravel inside---but it's actually quite hard to see inside (seems a little swollen to me? like the inner cheeks) He seems to be eating ok? I mean he's sucking food in (I fed him softened sinking shrimp pellets as a treat) So weird. Imagine a figure 8---his mouth looks like that---both sides are almost touching on the inside. Nothing furry or cottony, just normal colored mouth tissue to me.
His tankmate is a larger Black Moor named Shaft, who seems to be picking on him a little which got better when I fed softened floating food to the big guy and softened sinking food to this one. I've tried to give him plenty of hiding places----but he seems to like the big guy so much (who knows) and will follow him around even after being nudged by him.
I have pictures and Video (I'll link to youtube)
