Judging from the facts that it is 3".. I would say your full of it. Infact, I am 100% positive you are full of it.
A volitan lion would grow 6-12" in a year, easily. Think, before you talk.
You probably get a boner from feeding it goldfish, that is why it's going to die.
It is ignorant people like you who refuse the help of others because you think you 'already know everything.' Then you pass on your glorified wisdom to others, which then gives the misconception that Saltwater tanks are 'hard to keep' and 'the fish die easily' as well as 'They are so expensive'.. When really, they were just mislead. This then leads to people not even attempting to get into the Hobby. Then if they do decide to take Aquariums up as a hobby, it is people like me who have to work hard and use scientific evidence to dispell any myths that people like you have been blowing out their windholes for years.
If you want to keep your Saltwater fish half-assed, like you do, go back to the 80's.
I apologize for my comments, because I am an MFK community sponsor and I represent MFK as best I can. I tried to help, but this guys ignorance has really struck a nerve.
Learn to be wrong once in a while, Man..
