My wife and i kind of turned it into a little game.. see how many isopods you can capture each night. Then one night we couldnt find any more, gave it a week and still couldnt find any. The wife goes “wow now i have nothing to do at night” lol! I think in total we captured about 65-70 of them. I was about to get fish after 3 weeks and i found one more, which led us to wait until after thanksgiving just monitoring it for another month or so.Very cool. The biodiversity is amazing. Hard to say if I would enjoy catching the bad guys though.
