I've read netting such young fry not to mention a change of water could kill them. If you could get the water as close as possible in temperature, salinity etc. then move the entire tank into the new one with the fry in the water and mix the water a bit at a time, then let the fry swim out, they should be okay. Sine it's only a 1g tank I figure you could do this, submerse the whole thing in the bigger tank.

The filter is probably too strong, get a simple air driven sponge filter for a few bucks. If the filter can be turned down low then you can put some stocking or something over the intake tube.
