Maybe the roaches ate each other.
The first part of breeding crickets is separating the young so the adults don't eat them. They are far more inclined to do so.

I've only been in the hobby for a year, but I've owned quite a few T's in that time, and never had problems with DKS.

I feed my crickets apples. Let me clarify that. When I first started in the hobby, I fed them carrots and dog pellets, as is the norm. My crickets would last 3 weeks at a stretch. Usually only 2 weeks. Since I switched to apples. they are thriving. I've kept a large tub of crickets for over 2 months, with only a few of them dying.

The apples have obviously increased the longevity of the crickets, and regular feeding prevents cannibalisation.

I'm can't be 100% sure it is related, but my gut tells me it is.

Try it.

They have enough food, I doubt they ate each other, and if they did how would this lead to DKS? They eat a range of fruits and veg, basically whatever I have available at the time.

I have kept Ts for just a bit more than 2 years and feed mine crickets and i have never had a T get DKS or anything similar.

The DKS thing always crops up in UK forums and to be honest not too many people think it exists as a singular thing. DKS or Diskinetic syndrome is clearly a symptom of something else causing spasmodic behaviour. It "may" be from food but that hasn't been proven. It could come from systemic poisoning through air borne pollutants such as plug in diffusers and aerosols etc. It could even be down to general poor husbandry but this is all conjecture as there have been no solid facts as to why tarantulas display this behaviour. Another thing about being in the guts of live food. I have always been under the impression that it is locust that are said to be more prone to this? however... I have been keeping spiders for 13 years and have used crickets, locust, meal worm and dubia roaches and never seen so called DKS in any of my spiders

@ Dave Dawson, you seem pretty sure in your take on this. Where do you come across such certain answers as to how this is likely to go away post moult and also, hydration gel? Is that water crystals? the stuff that you can add to soil to retain moisture? If so then advising people to put this in with spiders is bad advice. Spiders are not able to injest this the way insects can and you can bet your ass that anyone who is using this on a regular basis will be complaining of "DKS" when in reality it is likely nothing more than plain old dehydration.

Dave wrote: By the sounds of it, looks as if the crickets on the market are not good. Iv heard of a few Ts now that
have got DKS.

When was the last time he/she molted? If its a small T its molting cycle is more regular.
If It has molted a while ago and is due for a molt in the next month or 2, the chances it
molts out and regenerates itself are good. But if has recently molted, I would be more
stressed. The thing about DKS, its a bacteria carried by small insects(CRICKETS). Once
a tarantula has injested the bacteria, the bacteria will carry on growing until it has completely
killed your spider. If the tarantula can molt, it will get rid of the DKS, nut if it has recently
molted I would try feed it as much as possible, also hydration gel mite help, as it has gelatin
which will give the spider some protein.

Good luck.

Im not sure on my answers, but the advice i gave is simiply what i have heard. If i was 100% sure
i would have a book like stanely. But what iv heard has made sense to me. A friend of mine, and
who is a really big and respectable member on this told me a story of one of his tarantula that
was almost on its way out. He put it in a container with hydration gel and it pulled thru and
was live and kicking. Im not what the hydration was that he used, but im assuming its the
ones we get at our pet shops. And i think, i couldnt get 100% info, but i think the hydration gel
has gellatine, which is protein.

As for the spider molting out and recovering itself, i was wrong. Which I admit.
My friend had a large Curly female that had DKS. It molted out and has still got the problem.

Im just repeating what i have heard from really big breeders and hobbyist that have had years
of experience with. ( Dont know if you know Onja from CZE).
