So I am in the process of upgrading my tank from a 20 gallon to a 55 gallon. I have never upgraded my tank so I am looking for some advice. The 20 gallon tank is established and fully cycled. I plan on using the filter media from the 20 gallon in order to hyper-cycle the 55 gallon. I also have driftwood and live plants that will be going in as well. I also bought some mesh netting to put the 20 gallon's substrate into and hang into the new tank to get as much of the BB i can to transfer. Unfortunately, I don't have room for both tanks, so when the 55 gallon tank goes up, the fish have to go with it. With all the things mentioned above, do you think the fish will be ok? I don't want any of them to die
Currently in the tank are 3 mollies, 4 fancy guppies and 1 baby striped catfish.
