Crawfish Tank

[EyeOfTheStorm]

While in Maryland last year, I thought it might be interesting to keep crawfish in a fish tank. I filled the bottom with masonry sand, and various rocks from around the area. I left on the charcoal filter that I had when I kept freshwater wish. I fed them sinking fish pellets, and occasionally, earthworms.

I found them to be extremely territorial, and aggressive to other crawfish in the tank. Each crawfish would chose a spot in the tank, most of the time under a ledge of a rock, beneath a rock, etc. In the end, I had more fun keeping these crawfish, than any other freshwater fish that I had previously. It was interesting watching them move the sand with their claws creating better living areas, or to defend against other crawfish when eating. Every now and again, I would attempt to throw in some fish into the mix, but the second one of the fish were still, they were dinner to the crawfish. The only species I was able to keep in the tank, were oscars. The oscars tried their hand at eating the crawfish, but a few snips from the claws ended that.

Here are some close ups of the crawfish in the tank. I allowed algae to grow everywhere other than the front and side glass, to keep it looking natural, but not to block viewing.

Awesome! They sound like their interesting. I have crabs with my fresh water fish. They are great to watch.

I have a heavy aluminum crawfish tank. I use a water conditioner made by Zatarains as well as a filter packet made by Zatarains. I feed them lemons, garlic heads, potatos, onions and andouille sausage. I keep the water temp at a constant 220 F.

I have a crawfish in my tank right now with a few feeder fish but i really want an oscar in there. I noticed that you said your oscars leave the crawfish alone now. is this still the case? and are they a good match?
