They reportedly get to ~19.7" on average, but they can reportedly get up to ~28".I was going to get a vlamingi from him and that is one of my dream fish! As of now my stock is a damsel, one clarkii and my 4 eels. I have a regal being QTd for me. I have a stock plan but would have to re consider with this fish if it does get 2 feet???
