I bought this critter box to experiment with trapping some fish. I still need to drill the lid and attach a fishing line to it but couldn’t find any tonight. I decided to just put it in there anyways for the fish to get use to it. Just for fun I squirted some food around and my cleaner wrasse was quite eager to eat so I squirted some into the box and in it went! I just tapped the door close and that was the easiest fish I’ve ever caught haha.
