I feel like second class posting anything FW on here but I understand SW has more muchness than FW has. I have a 41/2-5inch red fin shark that I would give to a new home with someone with a seasoned 4 or 5 ft long tank. I have had him for four or five years and he is in excellent condition. I recently went from a 56gal column to a 4ft 120 and want raise a red tailed shark for a change. He is a normal red fined/redtailed shark but not overly aggressive. Put him in a long tank with suitable tankmates and he will be a showwinner in your tank. Call me at 4193091091 and bring your own bag.
