saroj, if I may make a suggestion...when I had to do nebulization treatments for my parrot he absolutely did not want to go down into the tank (I used a 20 gallon glass aquarium with an acrylic top) but when I laid the tank on its side he had no problem being placed over onto the perch as I closed down the lid. I was able to cut the hole for the treatment tubing into the acrylic lid. I will post a picture, which may better show what I am trying to describe, if you think this is something that may help Jackson to like being placed in the tank.
