How close can Indo and Aussie torches get?

[LeafsReefer]

This is right after a water change with the pumps off so the torches are retracted. On the left is an Aussie Gold amd on the right is an Ultra Gold White Tipped Indo Torch that i juat got. Flow will direct the Aussie towards the Indo, but it isn't long enough to touch.

Is it OK some they don't touch, or are they too close?

Test it out. Most torches are fully compatible. When they are extended bring them close to eachother and see if the tenticles stick. If they don't you can keep them as close as you want.
