We have a single koi about three inches long and a year old. It has been living in a temp 50 gal tank indoors. We want to move him outdoors into a bigger pond and understand it should be a minimum of 250 gal per koi (Hoping to add either goldfish or at least one more koi for companionship) We have to do an above ground pond but have the potential to freeze in winter. how much sun should the pond get and what is best or easiest way to reduce risk of freezing? Thank you

We are planning a trip for August 2027, approx 7 days and want to visit both the big island and O'ahu. We have been to neither. How would you split your days? For the big island we want to visit the volcano and I just read about night swimming with the rays? For O'ahu we for sure want to visit Pearl Harbor, the cultural center and Kualoa Ranch. We are not huge on snorkeling however I wouldn't rule it out but not sure which island is best? Thoughts?
