right i have had 9 Asian aros in my comm and now sold them all apart from one so i have moved 8 aros in the space of 1 years so i think i know how to do it and what works and what doesn't
what you need is the big plastic bags LFS call them Koi bags
when you have the bag get a metal coat hook take your coat off the coat hanger
make the coat hanger into a nice ring shape then place the bag in the middle of the coat hook and wrap the bag opening around the coat hook
this will give you a nice round loop at the entrances of the bag which will stop the bag closing in the water
turn all the tank lights on bright with the bag and coat hook in the tank the aro wont see the clear bag in the tank as well with the bright light then make the aro swim throw the loop into the bag as soon as the aro swims in the bag head 1st bring the loop to the front tank glass and turn off the tank lights
let the aro calm down a bit in the bag before you lift the bag and remove the coat hook
then comes the next stage the bag will have to much water to lift out of the tank so place a hose in the bag and drain some water make sure you keep a tight grip on the bag top
lift the bag out of the tank and add more water if needed job done
i have tyred many different methods and this is the best by far
and yes i am a expert at moving aros now
i just copyed and pasted from the other thread
if you put the aro in a rubber maid or other solid container if the aro thrashes around then it will have a good chance of braking its barbels
plastic koi bag is what you need
