Are crabs reef-safe?

coelacanth,
hahah.. i do agree that bird wrasse can be destructive when adult size.. but as i dun have reef.. so, it still pretty ok.. using octopus is fine.. just make sure that it is not blue-ring.. very dangerous.. and the holding tank is escape-proof...


Liverock,
IMO, I find using one animal to consume another in order to get rid of the latter is not entirely a good idea....

I will worry abt what is going to happen to the predator when all its prey are eaten up?
Will the predator starve? Must I supply it with its natural food (prey)? Thus, the cycle begins...
yes.. i agree that using another animal to consume another is not really a good idea.. in my case, when i had the bird wrasse, it did the removal job for me and strive on tetra bits too.. they will consume anything.. but u have to consider the bio-load increase.. the alternative method would be to manually remove the crabs.. tedious..

[coelacanth]

but sad to say, manual removal is not possible as they'll somehow hide somewhere.

i quite agree with you that meddling with food chains are not appropriate, but thats life. fish keeping by itself is a chain breaking activity... []
