T.verrucosus babies need help urgent

johnson · Oct 26, 2004

Hi friends,
my group of T.verrucosus keep laying n I keep hatching them. From the day I got them till now there should be more then 1000 babies I hatched.

But I have a very big problem. The babies keep dying!!!!

I keep them in big group in big tub they die.
I keep them in small group in lots of small tubs they die.
I keep them in very small group in small cups they die.

I used the water from the main sallies tank they die.
I used aged water with anti-chlorine from a pail they die.
I used aged water with anti-chlorine with 2 gold fishes in the pail they still die.
In the end my 2 poor gold fishes also die!!!

Where did I go wrong?????

I noticed when they die they r coated with a layer of white coating. Once 1 baby spotted with the white coating the rest of the babies will die within the next 2 hours. My gold fishes die in this way too.

Currently I used a 1 ft by 1 ft tank with an air pump. Still trying very hard to bring up the babies. Situation does not look too good cos I spotted 1 baby die this morning again.

Can any kind soul pls help me out??

I'm the murder of a thousand babies

Still have hundreds of eggs waiting for me to execute them

That's a bit of a mystery. I am guessing that there is some sort of pathogen in your tanks that only affects larvae.

I did wash n wash the containers that I use but the problem still persist.

Question: Can I use the water from the parents tank??

johnson · Oct 26, 2004

I also notice one thing that when the babies r about to start dying the daphnia that I put in will die within minutes or even seconds.

I would say there is something in the water you rae using to rear them.

If they are being laid in the parent tank and the parents are ok why not keep the water from that tank at least you know it is ok.

You could set up a pond outside, let it fill with rain water then use the water from that as there will be a healthy ecosystem already established in it.

I would do some tests on the water you are trying to hatch them in and not use it to house anything until you find the problem.

Johnson - that sounds like an ammonia surge if the Daphnia are dying off suddenly. You need to make sure the water conditions remain stable.

mike · Oct 26, 2004

Daphnia are very sensitive to certain water conditions. They are used to test pollution in bodies of water. Maybe the local water has to do something? By all means try other possibilities. (Bottled water for a bit, Parent's tank water, UV Sterilized water)

Hi John,
just tested the water using tubifex worms. They die (become white) within minutes.

johnson · Oct 26, 2004

Thanks Mike, u mean boil the water??

johnson · Oct 26, 2004

Hi Killian,
the problem is I'm not sure is the main tank's water safe too cos I used aged water in another tank n put the females in there n they still lay.
Any recommend test for the water like ammonia etc..

johnson · Oct 26, 2004

I dun have an outdoor pond

chris · Oct 26, 2004

The white coating seems like fungus...try keeping a few in a fish breeeding trap in with the adults.

johnson · Oct 26, 2004

Oke Chris, will do so

john · Oct 26, 2004

Ammonia spike, or nitrite spike.

ira · Oct 26, 2004

it could definatly be an ammonia spike, espically if you are putting gold fish in the water before the water gets to the larve. Gold fish produce tons of ammonia and your probally should not be using them to age the water. Just get a good clean bucket, fill it up, and let it stand for 2-3 days and you will have nice, declorinated water. I have heard about people having trouble with cuadates and that declorinater stuff too.

If the probally continues, it may be your water has something in it that is bad for your newts (and maybe even bad for you if it is something like heavy metals or cyanide) maybe look into a RO/DI unit or a distiller.

johnson · Oct 27, 2004

Thanks friends. Will look further into the problem. Will also get another pail to hold the water n hope everything will go well.

jennifer · Oct 27, 2004

You didn't describe what kind of water changing protocol you have followed. You might want to try 100% water changes every day or every 2 days, along with a change to a fresh, cleaned container.

In answer to your question, yes, you could use water from the parental tank. You might also try leaving a few larvae in with the parents... some people have had good luck with that.

johnson · Oct 28, 2004

Hi,
I did 100% water change for the babies every 2-3 days but I didn't change the container. Maybe that is also one of the reason.

Currently I put in few babies into the parental tank n see how r they doing in a few days time.

Thanks

Verrucosus are voracious - make sure the larvae have plenty of cover to escape being eaten, or as I said, use a fishbreeding trap.
