Fish Spear Gun?

I need to remove a big Damsel that is causing trouble. It is very smart and has eluded all other attempts. I don't want to remove the rockwork and do not care if it has to die to be removed.

My thought is to spear it. I wonder about using a long thin metal shaft inside of a glass tube. The hollow glass tube needs to be 18-24" and the thin metal shaft 20-30". The end of the metal shaft would be modified with hooking barbs.

What d'y'all think of this idea and where could I acquire these items?

it will take a fairly large amount of force to spear a fish i think, enough that if you miss i would be worried about it damaging the glass/acrylic in the tank.

a 24 inch glass tube could be tough to come up with and would be fairly fragile.  you could find a 12 or 16 inch plastic tube used for pipetting though easily, i'm sure suzy has access to a few different kinds.

the shaft you can get thin metel down at home depot, or welding rods will work as well.  lots of options there and a little soldering or the barbs.

sounds like a jacque cousteau experience in the making!

Mark, is the problem fish the only fish in the tank..if so how about rigging up a small transformer to stun the jerk fish..think of fishing with an old telephone ringer. :)

Jon - you have weapon making skills.


I'm very interested to see if Suzy will contribute to such activity.

When I was a kid we found that some of our fireworks would still go off in a local canal.  Maybe you'd like me to come over with some bottle rockets!!!!!!!!!!!!!

"Stun the fish with an underwater explosion"  Wait until He floats to the surface.   

Sorry Mark, I couldn't resist the humor of the whole weapon and how do I kill a fish topic!   I wonder is there already a "101 ways to kill a fish book out"?

Geez! A spear? A BB gun?

 What about a little Ambien to gently relax him to sleep, then he can be gently removed to a kinder, gentler tank?

 (Like my lionfishes house? Even I think damsels are the spawn of Satan!)

 

Can you just capture it while it is sleeping?

I like the way Kevin thinks!

You guys are way funny.  You have my wife and I in tears.  I am quickly learning with some fish that once they go in, you tear the tank apart to get them out huh!  Good luck Mark.  If you need two more hands in your tank just call me.  Can't promise I won't come out without some corals though
