Fish trap

Extreme marine in Ventura rents a fish trap for $10 . You get it for 4 days with a $40 deposite. I have had this pest of a 4 striped damsel in my tank for like a year. Couldn't catch him. He was way too smart for a fish!! I tried everything but tearing down my tank.
This fish trap works Great!!!!! First day I fed the fish by putting the food in the trap. I left the trap door open.The damsel was too smart and didn't eat. All the other fish just went in and ate till they were full. Day 2, i thought I would just feed again in the trap and not try and drop the trap door. The damsel went in and out a few times so I grabbed the string and BAM!!!! Dropped it and caught him.
So if you need to catch a fish , this trap works.

I have found the soda bottle method has worked much better for me than the trap door/string method. I make them like this video, using 20oz up to 2 liter depending on the size fish I want to catch. I also cut off the threaded part of the bottle to make the hole just big enough for the fish to fit through.

I tried both ways and found that the trap door works really well. I caught my wrasse that way.

I had the same experience where all the other fish went in but the wrasse. after day 2 he started poking his head in but that was it. I finally dropped the door and when it hit his head he shot into the trap. I was so excited. it took a year to get him out. one time I removed all water except 1/2 and u still couldn't get him.

this was the easiest method... by far!!!

I had to buy one my self since I needed a large one
