If they ball up fighting and crabbing, it's fighting.
NOT to be confused with the hiss crab of saying 'c'mere!'
I would NEVER intro gliders IN a pouch. When you do that, they're invading the others' space, and that hardly ever goes well.
I'd suggest placing them in the bathtub, on either side. Have gloves, large fleece squares, and treats handy. Gloves ON and fleece RIGHT THERE to break up a fight. Treats for if all goes well.
I like to test the waters by, if all is going well, putting a bunch of treats together to see how they are with sharing food.
