HI seadragon,
get a catalogue from ' aquatic eco' , this is a aquaculture supply house in florida, it features one great net for collecting, this is the net with a clear acrylic handle and a soft mesh net, also quite clear. works wonderfully well. (sorry forget the references for the above).
Also try using a clear plastic bag, lay a rock in it with some chum or bait , find a fishy area . arrange the bag on the bottom and wait . Pounce to close and bag the fish. wrasses can be had like this. bigger bag for bigger fish, no limits...
