Q&A for How to Take Care of Crayfish

Yes -- crayfish can live fine with those conditions. Make sure to separate them when they're molting, as they frequently tend to eat each other.

You can usually put sinking fish food pellets in the tank at any time and leave them alone. They will eat fine without you timing your feedings for your crayfish.

Crayfish need a lot of oxygen, so it definitely good to have an air pump to add oxygen to the water. With this they can remain submerged 24/7.

They can! They also like peas and carrots.

As this article says, it's not recommended that you put more than one crayfish in a tank, but if you do, you should make sure they have enough space to themselves (10 gallons per crayfish) and enough places to hide. Also, if you do have multiple crayfish in one tank, make sure they are of the same species, or they are likely to kill each other.

Crayfish should not be fed too frequently. If you have the time to feed a bit every day or you're more comfortable with that, that's fine too.

About 30 minutes to 3 hours, but even then it is risky. Keep that lid on tight!

Yes, but you need to get a dechlorinator and something to balance the ph level.

Yes. But you need to add lots of places for them to hide.

Make sure to pick it up by its back. They might be able to reach back, but usually you're safe.

It is not recommended, because the crayfish or Betta may hurt or even kill each other.

This is all normal -- he is just wanting either more food or he is going through the growing stage.

Crayfish will be happy and healthy with your other fish as long as they have enough food and are in healthy water.

Crayfish can survive two hours without water, but then they need water immediately.

When their skin start to look loose, then you will know when they are going to shed.

Tap water is fine for crayfish, and the bowl should be cleaned at least once a week.

Try maybe catching some minnows or get algae wafers, my crayfish loved them. When they molt it means they're happy, but beware, crayfish sometimes can't come out of their molt and die, but do not touch or try to help them molt.

They may be able to grab the big flakes but it would be difficult for them to pick up the small ones. Plus it would take a lot of flakes to satisfy a cray fish's appetite.

You can buy crayfish food at a pet store. Shrimp pellets, or fish flakes would be good.

None, because crayfish have to live in a water level of at least 5 gallons.

They will be fine as long as they are the same size. After 4-5 weeks a few will molt and become much larger, that's when they will eat the smaller ones. If you provide lots of hiding places and enough food it will help, but eventually they will get eaten. They like to eat meat and green veggies like zucchini. I have found that mine do okay with the sinking shrimp pellets from the store, but do like an occasional goldfish.

Typically, no. If the Oscars are fully grown, the crayfish will become food.

They feel secure and safe in dark hiding places.

You can, but be sure to take proper precautions to make sure that the water is conditioned so that they do not die.

Crayfish can go quite a long time without eating, at least one month if the weather is cool. If you are having trouble feeding them regularly, put half a small, clean carrot in the water and replace it every month.

They can be determined by color, but also by size, diet, aggressiveness and other factors.

Yes, they can. They normally eat a lot of vegetables, and sometimes even plants.

It is, although your crayfish may not enjoy the pellets. If the crayfish won't eat the pellets, then you can try another kind of food.

No, the blue crayfish are Electric Blue Crayfish, white crayfish are Vanilla Crayfish. They are different species.

It depends on the filter. As long as the surface is agitated you should be okay. If you don't see the surface of the water moving then add an airstone.
