Rep: ODell has started on the right path
Question Adult newts eating daphnia pulex.

I ordered some starter cultures of daphnia pulex a while back and have been adding to a tank I have with both adults and larvae. Of course my objective was to feed the larvae, but it seems my adult notos really go for the fully grown pulex. I am not in the least concerned by this, as i find it amusing and don't see the possibility of this being detrimental, but i was wondering if anybody else has had this experience, with notos or any other species?

"If it moves, they will eat it."


I have seen this in a quite a few of the smaller animals. My axolotls on the other hand, start to ignore them right around the 2 inch length zone.

For real laughs, unleash some Daphnia magna for the adults. They will go crazy for them.

I new I wasn't the only one who has seen this happen, and got a kick out of it. I think I will try it with magna, when i get some. One of my males seemed to be chasing them (and catching them) all day, and now I can see why this isn't a regular practice (feeding of daphnids to adults), as he ate quite a few and put on almost no visible weight. Do you think magna would be more substantial in this respect?

Hello

All my adults newts, eat Daphnia (cynops sp., paramesotriton sp., triturus sp.) My big size newt is the Paramesotriton Fuzghonensis, and love Daphnia all Daphnia ( inclusive like the little Daphnia). My P.chinensis and fuzghonensis stay hidden many time, the days are Daphnia, it's easy see the newts.

Bye

My adult newts also love larger Daphnia and will happily polish off any spare. However, I tend to keep small foods like this in reserve for the babies - adults are equally happy with something a bit more substantial and I think it's a bit of a shame to waste my valuable Daphnia on something that will polish off an earthworm!

The smaller species(Lissotriton, Notos, etc.) eat large quantities of it in the wild and it suits their hunting style(mainly visual hunters).

Triturus cristatus and similar will go for them but are not as good at it as smaller newts.(depend a lot on smell for hunting).

My cynops love eating daphnia, and I love watching them hunting. In this video you can see some attacks:

Hello.

I confirm : I've never seen an aquatic caudate not interested by Daphnia.
And, depending on what the Daphnia actually fed on, they can be a carotenoid source (interesting for partly red caudates).

Friendly.

I've cultured both Daphnia magna and D. pulex and find that the pulex is far more robust as far as creating a stable culture and a quickly multiplying one, and the size difference between them isn't much. I do know that the CB N. kaiseri I just got love them!

Very small daphnia. For the first week or two I find bbs(baby brine shrimp) are the best food. Are your larvae 7 days old since hatching or since eating? If they have been eating for a week I think they could daphnia easier.

They should have no problem eating smaller daphnia. I like daphnia better because they will live in the water with larvae and won't foul up the water like baby brine shrimp does.

Do daphnia pulex and/or magna have enough nutritional value to be worth feeding to adult C. Orientalis as a supplement. I feed earthworms and tubifex/black worms to them right now.
