they did it again just a few this time. my lion head is not doing to wellhe swims on top of the water the rest are doing find could it be age he two years old or mabe older than that he was full grown when i bought him he cost $30 dollars his color is black and what is the life span of a lion head gold fish

i really doubt this fish is dying as he could live to be about 10!! youve gotta post this in diesise section to get proper help but heres a start!!!

If hes floating and struggerling to swim down hes proberbly constipated!!! feed him raisons with a pair of tweesers!!! works like a charm!

Its either what Mr. Fish mentioned, or he is just exhausted from the breeding process. Is it a female (the one that is being chased)?
