Learn To Taking Care Electric Blue Crayfish

If you are just getting into blue crayfish, then you might have some questions about electric blue crayfish care. I know that I did when I first got started. So below I’ll give you some tips that will hopefully make caring for your blue guy (or gal) a little easier.

Create a Comfortable Habitat

Crayfish are for the most part, one of the easiest aquatic pets to care for. They don’t need much, but you do want to make them comfortable and ensure they have a long, healthy and comfortable life.

To help keep your little critter safe and cozy, you will need to of course provide him with the right habitat. This obviously is an essential piece of electric blue crayfish care.

Some people will tell you he can just live in a jug with some water or something a little crazy like that. However, if you want to enjoy your blue crayfish and again, keep him healthy, I suggest buying at least a 10 gallon aquarium and creating a habitat that will be comfortable for your crayfish.

Just as a note, be sure to read up on setting up your tank before you put your crayfish (or fish) into the tank. This will include “conditioning” and “cycling” the water; which is the most crucial piece of setting up any fish tank.

Get a Hideout for Your Crayfish

Crayfish like to burrow and hideout. I often find mine picking up rocks and carrying them halfway across the tank to build their little hideout. However, make things a bit easier for them and buy them a hideout from any pet store and/or get some PVC pipe. Simply cut it into small pieces and add it to your aquarium. This will allow for your crayfish to hideout from any other crayfish or fish when they need to.

Additionally, crayfish do need a place to hide out when they moult. This is because they become very soft and vulnerable to other fish and crayfish who will attack them. So providing a hideout is another essential piece of electric blue crayfish care.

Choosing the Right Tank Mates

Okay, just go ahead and understand this, crayfish love to eat fish. So at some point they will catch and eat one or several of your fish. Because of this reason, you want to choose the right tank mates for your crayfish.

The perfect fish for your crayfish to live with will be fish that swim towards the top of the tank and/or fish that are fast. Fish that live or swim near the bottom of the tank or fish that are slow will definitely become crayfish dinner at some point. Having said that, I suggest red tail sharks, hatchet fish, tiger barbs, and danios as tank mates for your electric blue crayfish.

Other crayfish can also make good tank mates depending on the size of the tank. However, crayfish are cannibalistic and will sometimes attack and eat each other. Note, providing proper hideouts and keeping your crayfish fed can cut down on the chances of this happening.

Feeding Your Crayfish

Of course you will discover that your crayfish loves to eat. And eating is of course an extremely important part of electric blue crayfish care. Heck, who doesn’t like to eat.

You will want to feed your critter a sinking wafer everyday unless he eats a fish. If he eats a fish, he’s good… But you will probably want to run out and buy another fish.


How To Taking Care Freshwater Crayfish

Freshwater crayfish are beautiful and fascinating creatures to house in an aquarium. There are over 100 different species of crayfish which differ in color, from yellow to green and brown to red. Most of them live up to 3 years, though some may live longer. Nonetheless there is more to keeping crayfish than just throwing them in the tank. Even though they live in mud when in the wild, ensuring that the creature is both healthy and happy at all times is very important.

You must pay attention to a number of factors including, water chemistry and quality, whom they are sharing the tank with and diet. You must also understand that different species of the fish have slightly different needs, temperaments and behavior. Here is a comprehensive guide on freshwater crayfish care:

Water parameters

This is one of the most important factors associated with freshwater crayfish care. If the water conditions in the aquarium are not right, your fish may become uncomfortable or even die. So before you start keeping crayfish learn about cycling your fish tank. Here are some other great points to consider:

– Make sure you keep the water at a Ph. level between 7 and 8.

– Crayfish will do fine at room temperature water, but do not let the water get too hot, above (80 F/26 C).

– Crayfish thrive well in hard water. The minimum water hardness should be between (8-12 dGH and KH (140-210).

– Crayfish that are deficient in iodine usually experience problems when molting. The easiest way to make sure that they have enough iodine is to purchase marine iodine. A single bottle can last you several months.

– Just like any other fish tank, changing your filters monthly and 25 percent water of your water every two weeks is very important with freshwater crayfish care.

What do crayfish eat?

Crayfish are omnivores, meaning they feed on plants and animals; mainly fish. Usually pet crayfish are fed sinking pellets. In addition to that, vegetables like zucchini, spinach, frozen peas and collard greens are also great for crayfish. You can supplement their diet with feeder fish every now and then. Crayfish absolutely love fish. So don’t be surprised if one of your fish come up missing one day.

Also note that the fish require a lot of calcium to help them grow their exoskeleton. This basically means that in your aquarium, you should make sure that they are receiving enough calcium in their diet. Vegetables like spinach and collard greens are great sources of calcium. It is also acceptable to give them a supplement of brine shrimp or frozen krill once or twice a week.

How often do they eat?

Freshwater crayfish only need to be fed once a day. But plant food can be left in the aquarium indefinitely. If your crayfish eats a fish, and leaves pieces of the fish, make sure you remove the pieces quickly.

Can I keep crayfish in a tank with live plants?

Crayfish feed on anything they come across. Even though this may not be true for all crayfish, it is safe to assume that they will eat or destroy your plants. That is why it’s always a good idea to have artificial plants for your tank.


Most animals including crustaceans like freshwater crayfish undergo a process known as molting. This is shedding of their exoskeleton so as to accommodate the fish’s growth. If you note that the fish is hiding more or eating less than usual, it may be a sign that he his molting. When they molt do not remove the shell from the aquarium, he will consume it to facilitate growth of the new exoskeleton.

With these freshwater crayfish care tips, you should be able to have a healthy pet crayfish. Their lifecycle is very fascinating to watch and the fish will sometimes do things that will make you laugh out loud. Take care of them properly and they will reward you with several years of enjoyment.
