Yeah gatf are not as mean as what some say. Well fed and maintained including adequate swimming space, water flow, alot of o2 and excellent water cond. Follow those protocols and it will do fine. Depending upon how the tank is setup currently try to mimick that. If the side and bk walls are covered do the same in urs. Their downfall is how skittish some can be. Many have been lost due to fish spooking and slamming itself against a side wall. Do ur best to min and excessive activity around the tank, perhaps dim the lites some until it getz acclimated well. Beautiful gatf by the way. They are truly something special. I adore mine which is pushing past 18" atm. Im upgrading itz enclosure to a 1500 gal fbg tank with a viewing window. Cylinder shaped to deflect incase it attempts to run against the wall.
