Will red crabs eat fish

[chaibill]

Saw some red crabs at the LFS they always have them are they brackish? I don't think they could catch a small fish but will the bother my corys? Will they eat flake food that is in the gravel? will they burrow into gravel? Thanks I have been looking at them for a while but never sure and you never know what the sales person will tell you.
Thanks all

Crabs like meat, Im sure they would eat it if they could, remember predators have their eyes forward to stalk prey!

If you are speaking of the fiddler crabs that most stores sell they need brackish water to survive as well as a dry place to get out of the water.

They are brackish, so forget about keeping them with cories.

not true, i had 2 before, my LFs kept them in a fresh water tank, they said they were born and raised freshwater, i had 2 in my tank and they fed on decaying plant matter, and when one of my neons would die they would grab the corpse, carry it above the water and consume it entirely. they lived for a bout 7 months happily in my tank until i went away and the people i asked to watvh my tanks neglected my 5g in my room.

they dont need brackish water but would prefer it... i had mine for half a year until he passed away he would climb out of the tank and climb back in but would never venture away from it.

if the fish is slow then it's food im guessing but mine was a wuss. he wouldnt hurt anything.

they are scavengers so they will eat what ever they can get. more likley slow moving fish will become lunch.

This couldn't be right since red claw crabs need salt to do the bumpitdy bumperv:

They are a brackish species and also need access to land, but unfortunately are often marketed for freshwater aquariums. They can survive in freshwater and without access to land, however their life span is usually greatly shortened. As for being born in freshwater, most of them are still wild captured so I doubt that very much.
