they need to separate the not for sale from the sale items , not in different tanks , but in different ends of the tanks , one end for sale , the other end for his colonies , this keeps them in the same water when they frag them and everyone in the building knows whats for sale or not , the place in Romulus MI does the same ,i have been to both several times and still don't get my hopes up when i see a super nice coral in the tanks that i want . 90 % of the time ,,its not for sale. i still love both places and will go back to both . but i don't like the game they play with the not for sale stuff just so you will stay at the tanks looking , it keeps you in their place longer . I dont know the guys up in Michigan , but Todd is a great guy and very helpful every time i have been down there .
