So I have a 5 gallon cycled aquarium with 2 glofish. They are happy and healthy and haven't been sick once. I am fascinated with glofish and wish to upgrade to a 30 to 60 gallon aquarium. I've had this tank for 3 months and has been cycled. However I'm worried that if i upgrade my fish will get stressed or sick. So my question is, what is the best way to move everything into the new tank? I assume I use the same water and filter for a 30 gall tank? Advise appreciated.
