Crayfish tank/procambarus clarkii

[KilliNewbie]

So I am gonna do up a new ten gallon tank, dimensions of 20x10x12inch, keeping a pair of clarkii and is wondering what brand/type of filter is okay and what brand/type of lighting should I use? Filter cannot be strong-current as Crays prefer slow moving water, using floating plants such as elodea or camboba to prevent the Crays on snacking on the plants. Any other points i should take note of ??

Hi there,

I have been keeping clarkii for almost a year now and they are pretty amazing creatures to rear.
Below are some of my insights for the setup.

Strictly avoid plants. i had my crays hanging on my frogbits and tearing them apart, dirtying the water.

OHFs are ideal as they are easy to clean and don't take up plenty of tank space.
Crays are messy eaters and produce a large amount of waste thus OHFs makes maintenance easier.
Gex OHFs are pretty popular so you might want check that out.

Substrate wise, i tried both sand and gravel and both are a pain to clean up.
Barebottom will be the best for cleaning but that should stress the crays somehow according to some folks.
They need to grip onto something while moving around.

Next, ensure lots of hiding places.Ceramic pots, caves, wood etc.
Just ensure the decors are not too heavy as crays burrow a lot and the next thing you know, broken glasses or lobster marinate.
I personally likes those plastic pipes. Easily available at most hardware shops

Lastly, if you are going with OHFs, you will need to consider a hood or cover. They are amazing jail breakers.
Most LFS sells those egg crates that can easily be customized to your setup.

Happy craying!

I presume OHF are filter? I'm going with river gravel mixed with black gravel, Getting pvc pipes then siliconing them together, Small clay pots and some Root-like bogwood. Never seen egg crates in LFS before... Where did you get your p. Clarkii's? My lfs sells them but looks weak and sick

[orhlulu]

OHF = Over head filters
HOF = hang on filters

Both will be good. Hof if u have a tighter budget

As for egg crates, check with the lfs owner, normally it's hidden.

I got my clarkiis from a store beside aqua one in pasir ris. I think it belongs to aquaone as well. Wide selection of different colors.
Probably those you seen are under fed. As long as their eyes are intact, they can easily be groom back to health.

Just Googled for Aqua ones location and it says No.22 Farmway 2 (unit b1) but the map is Pointing 1-3km away from Whitesands Burgerking?

It's at farm 2 , turn left upon T- junction.

Ok, thanks a lot, will check them out after establishing my tank, btw, do your clarkii ever breed? And what's the estimation period between each moult?

[orhlulu]

Remember to share the tank and setup pictures

Moulting frequency is dependent on it's size and amount of food intake. Smaller ones moult more frequently or if u feed them regularly, they moult more often. Normally moulting occurs after water changes. I do 20% water change every week and somethings closer to 50% when the water is in a bad state.

Spotted of my females berried but the eggs didn't survive. Same thing with my CPOs.
Incubation period is around 30 days so it's better to house them separately but little changes might have stressed them up and thus they probably ate their own eggs.

You have CPO's ?? Thats Amazing !!! Hear that their on sale for $80 per pair ? Cpo was the reason i started Crays

[orhlulu]

Crays are very hardy as compared to CPOs. They are as fragile as they look.
Cute little creatures that are midlly aggressive
Wow, $80 per pair?
I was at C328 and saw several CPO going at half a red note there.
I got my CPO from C328 and NA. NA's CPO are better in quality.

Here are some pictures of my berried female and its tank mates. Took them out for cleaning last month.

Half a red note as in Green note? Hope C328 stocks them when i'm gonna buy them lol

[KilliNewbie]

Your pics of CPO's are so poisonous... Havent got luck rearing the young ones?

[orhlulu]

haha yeah a green note. C328 stocks them regularly.
Its hanging in little packets near the counter at the discus/ CRS chiller section.

Still trying. Probably gonna take out the males instead of the female now.

[KilliNewbie]

GoodLuck On your CPO's, Maybe can get some from you if they survives

[orhlulu]

Thanks bro. Still in the learning process. I am more than willing to give them out if the fries survive

good to know people spawning cpo. do note when they are 2 months they are quite sensitive to water conditions. no drastic changes.
they are more sensitive than crayfish

[KilliNewbie]

Wonder if you'd get a spawn by March Btw Freyster, Anyways to Secure a higher rate of survival in spawns?

[orhlulu]

Bro, i came across this deal earlier. It is a bit LOL but you can check it out if interested.
