    Hey Guys was thinking of a way to get those pesky crabs out of an established tank without a speargun or doing any remodelling, came up with this solution!
    [​IMG]
    Chopped a coke bottle in half and stuck the top in inverted, a bit of calamari and .... bob's your auntie!!! I've caught 4 in one night!
    put it in after lights out and next morning you are sorted. semms if you keep it upright in your tank, but with a ledge slightly above or wedged in rocks, the fish don't go in!!!
    Has anyone else tried this or has a different method!?

    Ummm, one word.... "patent". Seriously, I've seen so many traps, I can't remember what I've seen. I don't remember seeing this, but this seems ideal, and it works!

    Quick, change the post, I prefer "Pepsi" and only diet, as my sugar level can't tolerate the real stuff.

    Seriously a brilliant idea that you have come up with!!!!

    As a kid we used to catch small fish in local dams like this. But then we kept the bottle sideways.

    Yeah Riaan,
    I do think if you put it sideways in your DT it will probably catch fish.

    LOL Brent! I knew that this was good to catch fish - but never thought of using is as a "crab trap"! ;)

    Do you think something like this will work in catching those elusive specimens in the rock pools we were talking about? ;)

    2L coke bottles do work if you in a rush and don'thave a net. Have one huge net like 500mmx500mm by about 700mm deep as a positioning net and either a smaller one or a chase stick in your other hand! ... and go slow!.. got a couple of goldies like that this weekend;)

    Good job Brent, I reckon I'll be using one in the next few weeks. Amazing how a small change in orientation and you catch a totally different organism. :thumbup:

    Brent - I really NEED to bum your "nets" from you when I get there next time. I paid R160 PER GOLDIE (the same that you caught!)! And I bought 6 over 2 months - where 3 died :(

    Hey Colbar,
    What I have noticed is no crabs are actually bad, they eat any algea, detritus and generally are great cleaners..... but......!!!!! they can occasionally grab a small wrasse, goldie, or even nibble on the corner of a clam!!!
    I've had over the years the little white and red ones, they tend to stay inside a piece of sps coral and don't get to big!
    Best is too post a pic so the guys with the most crabs:whistling: can confirm he's a goodie!!:lol:

    Eish Jacques, can see why you can get annoyed!!!
    I'll rent you nets at R160 a day, so you better catch at least a few to get your moneys worth!!! haa haa:lol:
    No problem! Hope you can hold your breath though, oh and better go for some swimming lessons before you come coz you can't dive deep with arm bands!?!:razz:

    I know it is so simple, somebody I'm sure has to have thought of this before though???? ... ok now we have to work out how to make a fish trap in the sea that only catches rare stuff ( gems, tiger angels etc etc!!):p.

    i think it is good practice to post a pic of you catch or let us know if you were not successful.

    A regular drinking glass works just as well, particularly if you have a sand bed. Just stick the glass in the sand or put the rim against some LR, weigh down some smelly bait inside and leave overnight. The crabs can't get out because of the slippery sides.
