I am thinking about buying a crawfish Will it harm the other fishes in my tank2007-11-24 23:34:41

I have a 55 gallon tank. I have a flowerhorn cichlid and a jack dempsey, 2 catfish and some other cichlids. I want a crawfish to help clean my tank, but i am afraid they might kill the fish at night or pinch their fins. Should i buy the crawfish?

Answers:

After reading the other comments (as I always do) everyone brings up good points (and Hillary, a crayfish & crawfish are 1 in the same)

It's a flip of the coin really - if your other fish are bigger than the crawfish they should be okay, BUT they also might try to eat the crawfish as certain cichlids tend to be very aggresive.

Go to a small creek, lift up a rock and get 1 or 2 with 1 of your fish nets - that way you won't feel bad when 1 of your fish eat a $10 investment.. or get some snails, they might do the job..

They eat anything smaller than themselves & dead fish.

It will try to eat them, but if they are healthy and aware, it won't be able to catch them.

I had several in a 55 gal tank for several years. One eventually ate all the others and a couple of slower fish.

Are those other fish freshwater fish? I think a crawfish is, and I'm pretty certain the catfish is. I don't know..

We tried putting a crawfish in our pond. It didn't kill the fish, but it floated to the top dead in a few days. I was goofing off with some kids here at a Crawfish boil.
