Hi all,

I originally posted this in my local club forum <a href="http://www.reefcentral.com/forums/showthread.php?s=&threadid=940129" target=_blank>here</a>. I thought I would reproduce it here for all you DIYers, though.

I recently had a pesky flame angel who ran rampant in my tank nipping at almost all of my SPS. I didn't want to break down all my rockwork to get him so I read up on ways to trap fish. I got the idea for my DIY trap from a really great thread started by Anthony Calfo on catching critters. I put the trap in my tank on a Wednesday evening and fed only in the trap. Then I fed through the trap on Thursday and GOT HIM! The trap worked like a charm. Total cost was around $2, mostly because I had a bunch of spare parts laying around to build this with.

Here are some pics of what I did:

I purchased a smallish rectangular food storage box from wallmart ($2), cut a hole, and installed a bulkhead toward the back of the box:

I cut out a piece of eggcrate big enough to cover the opening of the box to serve as a door to the trap:

I drilled two holes in side of the box, and attached the eggcrate with 2 zip ties:

Then I attached some string to the upper third of the eggcrate door, attached some pipe scraps to the bulkhead and ran the string through the pipe:

When you pull on the string, it closes the door tight! The holes in the eggcrate allow it to move through the water quickly.

I made the whole thing (pipe + box) such that the top of the pipe was above the water line, but low enough that I could close my canopy. I also made the string fairly long so it could hang down the side of the aquarium. To use the trap, I just left it in the aquarium and I dropped some yummy food down the pipe at feeding time. When I caught the flame angel, he just kept munching away at the food -- so it was a low stress capture. <img src="/forums//forums//forums/images/smilies/biggrin.gif" border="0" alt="">

Here is the Anthony Calfo thread where I got the idea. Many other capture methods are also documented there (i.e. GREAT THREAD!):

crumbletop, I just found this thread. I have 3 tangs that I want to catch. My husband is going to make one of these. Thanks!

Great!

A friend of mine just used it to catch a pesky fish in his tank that he has wanted gone for more than a year. The Tangs went in right away and he could have caught them easily. The other fish was more cautious but he got nabbed. I hope you have similar success.

Cool, I made one a while ago as well:

Similar design, uses a line to release a trap door, also has a hole for placing food inside the trap. This one was made to clip on the euro bracing of my tank.

crumbletop, that's good to hear. I'll be curious to see if my tangs jump right in. They are sometimes funny.

sphelps, cool. That looks a little more complicated then the other one. :)

I'll have to keep you guys posted on how it goes. :)

Nice! Very clean.

Did you have any problems with the sliding door jamming, or not going down really fast? Some of the quicker fish can dart out in the blink of an eye. I've heard of problems with sliding door traps jamming or moving too slowly at the most inopportune times.
