DIY fish trap

[aruns]

I ran into a situation where I had to catch my larger yellow and mimic tangs in my 150G when they started constantly harrassing a newly introduced smaller purple tang

I balked at those fancy 50-80$ fish traps and decided to look up DIY.

Certainly not my original idea but this worked beautifully - took me two days to catch them, tempting them with nori.

$6 Petco small size pet keeper
Some fishing line to control trap door
Frag plug + nori + rubber band + fishing line to dangle the nori and be able to swing it to where I want
Some sort of aquarium magnet to secure the pet keeper, I used my tunze magnetic scraper
Turkey baster to inject food
Drill hole on side of pet keeper to inject food via baster

What I observed
- wrasses were the smartest. 2 of my fairy wrasses immediately figured out how to go in and get the food. My yellow Coris and melanarus were super cautious and never ventured near the trap
- my clowns kept pecking at the sides and never figured out how to get to the food, lol.
- my tangs were somewhere in the middle. On 2nd day they tried but couldn't figure out how to get the food. At this point I dangled the nori near the mouth of the trap and let them eat for a day. Then next day, did the same but when they started eating swung the nori into the trap and they both followed inside. Super stoked when it worked

Nice! Awesome write up.. it’s crazy to think about how some species of fish are so intelligent. I use a long acrylic feeding tube and my clown always attacks the tube. Haha makes me laugh.

Thanks . Nevertheless, they all do have interesting personalities.
