I had read that about my orange cray as well. I did occasionally feed it "Color Enhancing" pellets. All that means is that it contains extra krill, which adds a red pigment (fun fact: flamingos are born white, but turn pink due to their high krill diet). It always stayed orange, but whether or not it was because of the food I couldn't say for sure.

Food that is high in spirulina is supposed to help with the blue/green pigments. It might help... certainly wouldn't hurt. Just make sure its also getting enough calcium in its diet as well. That's probably more important.

What foods contain calcium? can I just throw in a calcium bone once in a while or is that a no go?
Also when you say spirluna do you mean that green stuff that people use to feed their marine fish? that makes the water go greenish

Here is what I feed my cray (in addition to some other things):
Aquarium Food & Nutrition: Hikari Tropical Crab Cuisine

I was able to get that at pretty much any LFS by me.
I was also able to get mine to eat vegetables that are high in calcium, like spinach and kale.
I never tried it myself, but I do not think putting a cuttlebone in the tank would help.

Ive only ever done freshwater stuff, so Im not familiar with what kinds of food are fed in marine aquariums.
Spirulina algae is an ingredient thats pretty common in freshwater food flakes/pellets. How much of it there is will vary from brand to brand. As with any list of ingredients, the closer to the beginning the higher the percentage of that particular ingredient.
For example:
Sinking Spirulina Wafers

Spirulina is listed second here, so its uses more than most other types of food. Something to look for when you're figuring out what to get.

I honestly don't know for sure. But there are a couple of things that are known to help keep colours bright. Spirulina algae is one, another is astaxanthin, [ Naturose powder]. You can get both as powder and maybe mix up some home made food, or buy foods with one or both of these ingredients.

They can, usually after a moult, a limb may reappear. Not for sure, but certainly possible.

Beneficial bacteria how long for it to grow?

Yes they will regenerate all of their legs. It'll take time though.

If it is warm enough for you, it's warm enough for them, so I wouldn't be too concerned about temps, unless it was getting below 40 F. I think they can survive short periods in temps near freezing, but not for a long time.

Welp I bought a heater for him anyways its a 100 watt heater for a ten gallon tank since the temperature in my tank is always dropping and raising I feel it would be stressful for my crayfish if he had to deal with temperature change constantly. Would setting it at 68 degrees keep him at a safe temperature it says this heater is rated for 25 gallons so i feel like the heater will make the tank around 74 76 degrees. Oh and can I keep the crayfish with live plants? his tank looks so dull its just sand and a big o' lava rock in the middle for him to hide in. sorry for asking so many questions D: i just want my cray to live a long life
