I have both invented or maufactured many, many, things and I have to say most everyone of them works absolutely fantastic.. This is one of them, and if you dont have one you best build one of these, only because some day you will need one. Removing anything alive in a heavily stocked tank, sick fish, transfering between tanks, trading, moving aggressive live stock, protection of corals... on and on.
Dollar Store Trap,
This works like no other way I have ever seen. I made my first one some 30 plus years ago. Stepped on my last good one I had it for about 18 years. When I made one out of a pink plastic jar, they did not like the color I found out fast. So I made a new one, you to can catch any fish in no time at all. This is my total investment it is just shy of $13.24..! And that is if you don't have any of these items at all. There are two sizes of these jars for $1.24 each at the Dollar Store. I chose the smaller size as it is perfect in any tank I have, due to the tons of live rock.. tons. You CAN"T catch anything in a clean manicured well stocked tank with a net... Good luck
The way it works:
Place the jar with the magnet glued inside of it, and the foam on the top of the jar. You just lower the jar down in the tank, the open end with the foam Vertical with the sand bed. Place the other outside magnet on a string, to the jar magnet they will stick together that will hold the jar in place (one magnet inside and one magnet outside on a string). I use up to 10 foot string. Put shrimp or clam into the inside jar.. And sit in your lounge chair and wait until the fish you want goes in the jar. And then pull the outside magnet on the string hard and fast, the jar opening will tip up immediately and float straight up in one second and float up to the top of the water FAST. Your fish or shrimp can NOT GET OUT.... There is no better way I have seen to both catch and seize any fish or shrimp of your choice.... Been doing this like I said for 30+ years and it works like no other... I just keep hearing about all these people with tanks that cant catch a fish. Trying for days and days at times. In 20 mins total max time I can get anyone of them. And I have some 300 lbs of live rock and corals everywhere!

This one came out perfect, best one I have ever made to date. Just wanted to share this to all. Happy Reefing
The list:
Plastic Jar $1.24
Neodymium Magnets, I use Rubber coated. (a pair) E-Bay (Out of Texas) $3.00
** You can use any type of magnet as they will be in the water for 5 mins max. Then just dry them off. They won't hurt anything at all. Just don't leave them in the ole tank as they will rust over time.
Foam Door Draft Stopper (Ace, Lowes, Home Depot) $8.00
Super Glue or heat gun (Dollar Store) $1.00
String, Braided Fishing line, Rope... lol
Razor Knife or a razor blade
One Larger Rubber band
And just 20 minutes of your time.
The foam that I used is closed cell foam and there is a picture of what and how to get it. It works perfectly and bends fantastic very little effort if any..! Bottom Picture!
Use this foam! I don't know if I could ever find anything that would come even close to working like this did...

I will post a video of it working and catching fish and peppermints very soon..
