Removing a fish

Hi there, I may need to remove my lawnmower blenny. It has become quite aggressive and is the main suspect in my only fish death so far, although I believe he has mortally wounded my royal gramma too. He picks on snails and crabs on the sand too. Any advice on how to remove it? Am thinking of putting the net in the water and wait until feeding time, it comes to the top to take flakes. Hopefully would be able to scoop him up. Any other tips?

Leave the net in the water for a day so the fish get used to it then put the food in the net at feeding time and they should swim right into the net.
 
How big is your tank? FWIW the High & Dry method outlined in the link below has always worked well for me. You might be able to net the fish out without draining the tank, but I would expect that Blenny to stick to the rocks on the bottom so you might be in for a bumpy ride. Good luck!

this does make it easier.. also this fish likes call a hole in a rock home.. I have caught them in the past by removing there rock ... In my tank when you put a fish in . its in for life ...
 
Are you sure it is the blenny? I never had a lawnmower blenny that attacked other fish unless the other fish is also a blenny or something that looks like one. Plus, I am not sure if their combtoothed mouths can kill other fish.

Only had 2 deaths, six line wrasse and royal gramma (probably as can't find it anywhere). Both had large cuts on their side. Unless one of my shrimp did it or hermit crabs? Lfs guy thinks a bristle worm could have got the wrasse but that wouldn't have got the gramma as it always stayed at the top of the tank. Blenny is obvious suspect especially seeing his aggression towards snails and crabs.

bristleworms don't kill things. Can't. Blenny is a possible. Usually in a 100 gallon tank they're good citizens. But a slash or cut is usually a tang or sometimes a crab. Red spot may be rabbitfish or pistol shrimp.
