Skiptons is going all fish, with big plans to add more tanks. They usually have excellent stock (healthy). They will not sell a sick fish which is reassuring. Their plant selection is hit or miss. A hit if you get there when an order comes in, a miss if it is picked over. They will order whatever you want, which is nice. They have several dedicated freshwater employees that really now their stuff and it fun to shot the breeze with them. They also sell RO water for 50 cents a gallon, which is good for me as I don't have room for an RO unit in my apartment.
Tropic Isle is nice, but far from me and have to pay tolls on the Mass Pike to get there. Lovely pets has some good fish and plants, but again, far from Boston in Quincy (a nightmare trip there and back in the normal Boston traffic).
I do wish we had a big store like Marine Depot near here, but alas, we make do as seems to be the inner moto of all New Englanders.
