Keep your LR in aquarium water (in pails) while you are catching your basslet. Make sure you don't kill the nitrifying bacteria in the LR. I wouldn't reccomend removing ur LR though. Too tedious. Just snag it while it's sleeping or set a trap using a small plastic tank with a small door in the hood.

Leave some food in there and try to lure it into the small tank once it's in there. Reach down and close it quick. or perhaps use a net and put some brine shrimp in it.

Oh your talking about a false gramma? haha my bad. But my methods works just as fine though. IMHO bicolor pseudochromis are beautiful and rather peaceful fishes. You shouldn't have any problems with their aggression. add a damsel to your tank and it willbe less aggressive(size intimidation). However they are known to defend their territory against fishes twice to thrice it's size. So I think u should add it as your final fish( or at least not the first few). Now you can take it out rear it in another tank(maybe your Quarantine tank) and add the fishes that you wanna keep in your main tank(that are non aggressive) then reintroduce your pseudochromis to the main tank> Then it will see the area as foreign territory and not show aggression to other tank mates are they were there 1st.
