Sadly My Dojo Just died from an Ich outbreak :'( as tough as they are Ich is actually a pretty big weakness.... I plan to get a new one soon and his name will be Confucius II Ill get 3 this time instead of just the one...
i've eaten many of these as a kid. they have many small bones, but if you fry them, you can eat the bones. my mom would give me a small one out of the batch she would cook to put into a water bottle or something so i can play with it. good times.
