Yes I know there have been many threads on this, but I am not finding specific info on it. Most of the time I read "It grows very fast", I honestly don't know how fast is very fast. I will be honest with you guys that I am guilty of wanting to put a blue hippo tang(hepatus) in my 125. I do find it hard to believe that a fish would grow from 3/4" to 7-8" in say 7-12 months. That seems pretty far fetched, for a fish that lives a fairly long time. I would more or less understand that growth if it lived for two years. My plan was to buy about a 1/2" blue hippo for my 125 and move it to my 240+ upgrade within the next three years. Local people have said that it should be fine as well as another forum(will not mention, no source is better than the other and I am looking for an overall view at this. You can't do a science experiment once and say that it works or doesn't work. So need multiple sources for this before I do this). So please give me your experience, starting size, end size, and length of time it took for the growth. Pics would be amazing if you have them!
