Thanks for your reply .... I'm really keen to learn from this because I love my Clowns, he will be missed, I have 4 others still so I'm hoping they won't get same thing what ever it was .... I read that clowns are better in odd numbers thats why I had 5 ... Symptoms of Deceased Clown: First thing I noticed was he kept loosing his balance while hovering 3" from the gravel bottom ... He was off his food ... No physical differences except for his eyes, on his last day he went blind I'm sure becaues they were glazed over & he bumped into everything... plus he was panting very fast ... Does any of this sound familiar to anyone?
