SRC Member hippo Posted July 31, 2004 SRC Member Share Posted July 31, 2004 just to share with you pple. Item need: 1 x 1.5ml of plastic bottle (1) cut 1/3 of the upper part of the bottle. (2) cut 3/4 from the bottom part of the bottle. (i.e. center part of the bottle is not needed) (3) force the upper part into the bottom part of the bottle. (4) ensure the entry of the bottle is slightly offset from the center of the bottle; to allow the crab to crawl in easily. Quote Link to comment Share on other sites More sharing options...

SRC Member hippo Posted July 31, 2004 Author SRC Member Share Posted July 31, 2004 FAQ: Q:When should I use it? Ans: Crab more active during the night. Q: Can use smaller bottle? Ans: Yes, you can. (6) Take note: place this trap into your tank where it sit on the sandbed. place it in such a way that small fishes or shrimps will not get into the trap. (e.g. place against rock wall; blocking the large opening. (i.e. crab can make its way tru small holes from the rocks into the trap. Cheers.

SRC Member hippo Posted August 1, 2004 Author SRC Member Share Posted August 1, 2004 Cool idea, but how long did you leave your trap in he tank before you manage to catch the crab?

Sorry to hear that. Holes at the trap area is good for water circulation. In case thing like that happen again.. Quote Link to comment Share on other sites More sharing options...
SRC Member neokn Posted August 17, 2004 SRC Member Share Posted August 17, 2004 Still didin't manage to catch the damn crab. Quote Link to comment Share on other sites More sharing options...
Tiny Tears Posted August 18, 2004 Share Posted August 18, 2004 yep, i tried it too. In the morning the food was gone, and no crab. I blocked it against the rock to make sure the shrimp would not go inside. The trap was fully submerged under the water, maybe that was the problem. Sigh....
