Titchfield very good and staff good! I would suggest north end aquatics on Kingston road in Portsmouth, on the corner of powerscourt road. I know the one in gosport and have to agree! Also I would strongly recommend going further afield to eastleigh and look in tropical paradise! Amazing corals and I found the people in there very knowledgable! Other than that- creature comforts in totton, Maidenhead in fairoak, aquajarden in fairoak. All a little trek from gosport but worth a look! Hopefully someone else will chime in with some that I have not heard of and I will be taking a look this weekend!
