Can betta fish live with fiddler crabs?

Answer 1

if you have a very aggressive betta fish, placing them with any kind of crab is probably not the best idea. Crabs, even if they are mostly non-aggressive, can rip a betta's long tail and fins to pieces! Bettas could also bother the crab, and then you have a full blown fight on your hands! If you really want to put them together though, watch them carefully for any signs of aggression.

Answer 2

Yes, or your Crabs would get lonely. You would want at least 4 and more Crabs in one tank, 2 Male 2 Female. I actually studied about crabs in tanks a few weeks ago. So this should really help, I hope.

Answer 3

The only crabs I know of are salt water creatures so they certainly would not live in freshwater with goldfish. If you have a freshwater crab however, and if they have the same habits and diets as Marine crabs, they still should not be kept with goldfish because they would be constantly cutting chunks off the poor fish for food.

Answer 4

I would not advise it. Crabs eat fish and will rip pieces off slow moving fish like Bettas.

Answer 5

I wouldn't recommend it, and I've learned from experience. Crabs (assuming you mean fiddler crabs?) tend to kill or seriously injure fish and are best kept only with other crabs.

Answer 6

Yes, I bought one betta two hours before and its become my crayfish food
