Thanks. He is an older fish, about 5 inches. He is still growing too.
I have also noticed that my fantail has some 'thickening' like what daryl said.
JohnF, your fish could possibly be a ryukin oranda mix

Anette, It is possible that your fish could have some headgrowth. Dont worrie about 'hijacking' any threads, or at least mine any ways

btw, angus is very beautiful. love the bright red color!!
