Acrylic tank makes a cracking sound at night

  • We are currently upgrading MFK. thanks! -neo
Too late sold it to someone whose using it for their bearded dragon. Got what I paid for it. Going to save for a monster tank. I have a 75 gallon used acrylic that I'm working on setting up. All the fish are in a 55 gallon and it sucks to go from 122 gallons to 55 gallons.
