Question by FishLoverGuy: I bought a crayfish. It’s eating my other fish! Can I stop it?
That up there ^ pretty much says it all. It’s in a 20 gal tank. I had a gold gourami (3″), a chinese algae eater (2.5″), a goldfish (2.5″), and 2 golden wonder killifish, (1.5″ and and 3″). Now I only have the gourami and the larger killie.

Best answer:

I had one before and I had the same problem. It used to eat everything with it. There was no stopping it! Eventually one day I came home from work and it had escaped from the tank and crawled halfway across the room towards my bed. Pretty scary!

What do you think? Answer below!

   I suggest you put the crayfish in a separate tank.

   Well, the smartest thing to do would be to get the crawfish his own little tank and start over on your fish. If you like the crawfish better and he has already eatten all of your fish, then get yourself another crawfish and just keep those and no fish.

    Separate the crawfish from the other fish. It sounds like you have a bunch of slow swimming non-aggressive fish. Those are just asking to be attacked. If you want fisf with your crawfish, buy fast swimming semi-aggressive fish. But I wouldn’t advise putting anything with it.

    No you can’t stop it unles syou get tank dividers because they usually the crayfish feel dangered and attack the other fish and eat them for protection. I really recommend the tank divider it will really help your other fish!
