Crayfish Too Aggressive?

[seacreature]

I have a 55g tank with one rope fish one neon tetra one goldfish and one crayfish. I recently seen him attack my goldfish when it was feeding time. He grabbed a hold and ripped his fin a litte bit. Do you think he should be moved?

Yes, most crayfish will nip fishes fins so they are best in a tank of their own.
Also, there are some issues with your stocking. Goldfish are coldwater fish and should not be kept in tropical tanks. Neon Tetra's are schooling fish and should be kept in schools of 6+. I think that your rope fish is okay but I don't know enough about them to advise.

Crawfish - will use their claws to rip at, and potentially kill, their tankmates.

This is what you were advised a few weeks ago. Yes you need to remove it.

The rest of my advice still applies too.

This sounds familiar....not meaning to be rude, but what do you think you should do....

I have decided to move the crayfish to another tank. its a ten gal tank. it has to be cleaned out and cycled. also going to add more tetras. About 6-8 more. I haven't noticed him ripping fins anymore tho. My goldfish has been doing well as far as water temp. goes. thank you all.
Adding the tetras to my original tank lol.

The Goldfish may be 'doing fine' in relation to the water temperature, but being a coldwater fish, it's metabolism is designed to be really slow. Putting it into tropical conditions speeds up said metabolism drastically shortening the life span of said Goldfish therefore increasing stress put on the animal. After all they are designed to withstand temperatures of up to 4 degrees celsius and possibly lower in ponds in the middle of winter.
It's like taking a polar bear and expecting it to live in the tropical rain forest, it might survive, but it certainly won't be happy nor will thrive in the environment
 
It's not if the crayfish will nip fins, it's when.
 
I don't want to come across as rude but if you ask advice on this forum, expect people to pick up on the welfare of the animals concerned, it's one reason I love this forum - everybody cares
 
Sorry for the blab

as other have said crayfish can be quite asgressive and i would be pretty worried about the ropefish eating the neon and the gold fosh depending on the size of the goldfish...

A bit more info for you. A goldfish should live for 20-30 years. Seacreature, please bear that in mind when yours dies, which I would estimate would be no more than 5-6 years.
