Hello guys, i am new here.

Just to make sure first, are these tubifex worms?


Sorry for the bad quality of the image, my cellphone isn't the best of models.

Anyway, next question is if i have heard numeros times that tubifex worms are not very nutrious and good as food to feed your newts, i would like to ask why and what adverse effects would it have if i use this as the primary food source(for my newts) for long term.

And also i would like to mention that my Chinese fire belly newts do not like to eat dry food or frozen food and only eats live worms and the only worms available in my area are tubifex, so what can i do about this?

It's impossible to tell from such a blurry photo.

Tubifex are quite nutritious but they contain fatty acids which make them a bad choice of staple. Of more concern are the methods for growing commercial tubifex. They feed on anaerobic bacteria and therefore thrive in polluted waters. Commercial tubifex are often grown in effluent run-off from fish farms and the risks of them carrying disease is high.

I use them from time to time when rearing larvae and have never had a death I could attribute to them. For adult newts you're much better off using live earth worms (chopped if necessary) or training them to feed on frozen blood worm.

Oh, and welcome to the forum!

I took 2 more pictures with my cellphone, these 2 are clearer.



Is it possible to identify them now?

The problem is that i don't know if my chinese fire belly newt is a juvenile or an adult, i just bought it around 2 weeks ago from a pet shop(which only sells aquatic animals). I don't even know if it is captive bred.

It's hard to tell if they are tubifex or blackworms, or perhaps bloodworms. If it were the US and they were alive, they would probably be blackworms, because bloodworms are not sold live in the US as far as I know; but from what I've read, they are available live in England or Britain or whatever it's called.
But as your location is Singapore, I don't know what is commonly available there. Does anyone?

If they are pretty red, they are probably bloodworms. If they are brownish or darker, they are blackworms. I've never seen live tubifex, but I think they are brownish as well, perhaps a bit lighter than blackworms, but I don't believe they're red. Bloodworms seem also, to my eye, sort of segmented, whereas blackworms and tubifex are like smooth wiggly hairs. Does this help? If anyone can elaborate better than I have, please do.
If they turn the water red when they are dead, then they are bloodworms.

Hello Tigerpaw, I really can't tell what worms are in the pictures, but hope this photo will help you.
The worms all bunched up are live tubifex, the darker one on the bottom is a blackworm. Don't have live bloodworms here where I live.

Tigerpaw - I would say that your worms are Tubifex, or something very closely related. They are not blackworms, and they are not bloodworms. As Mark said, tubifex are perfectly nutritious, but some people say to avoid them because of the filthy places where they are grown.

Nice photo, krk. Do you grow your own, or is there a place in HI that sells them?

Hello,

All worms shown in the pictures are tubifex. Tubifex are red and thinner than blackworms. I would love to get a hold of some tubifex here in the US. There is a tubifex breeder in Singapore who is producing them in a controlled environmet and they are not raised in sewers. The problem is I have to buy 100 pounds of them to get them into the US. Anyone on this thread in the US with tubifex, where did you obtain your tubifex?

Thank you, Lon Langione e-mail - lonlangione@comcast.net

    @ChocoUniversa, Buy some ammonia and an eyedropper from Walmart and a water test kit for ammonia, nitrites, and nitrates. Figure out (through testing) how many drops it will take to get the ammonia level to the test's maximum measurement. Add that same number of drops every 24 hours. Eventually, the ammonia will start to go down as it's converted to nitrites. Keep adding ammonia. The nitrite levels will spike for a while and then they too will start to go down as they convert to nitrates. These you get rid of by doing water changes, which you should be doing anyway throughout the process. Once all of these are at low levels, your aquarium is ready. It takes about a month, maybe two (mine took a month and a half). Be sure to add ammonia until the day of or the day before you add your axolotl.

    Hey guys, this is my first time using this so bear with me. I have an adult axie who looks like he’s developed some fungus on gills. It’s still really small and only on one part. I put him in a 10 gal quarantine tank with an Indian almond leaf. I want to give him a black tea bath but not sure if I can add my black tea to the tank with the Indian almond leaf in there. Any advice?

    @BChen3695, what are your parameters and temp? The fact that they're raised bumps could indicate fungus or bacterial infection.

    @XxJennXx, I don't believe so. They are closely related to tigers and my tiger doesn't brumate. I think first year they might but after they see they aren't needing to, they should be good. They might try and hibernate to, mine did for the first year but now I see him crawling around right now.

    @Pookisoo, The refrigerator is a good hospital for tigers.Temperature between 7 and 2 degrees Celsius can stop bacteria. If necessary or if you dare 0 to -2 can also help.Reduce the temperature in a few days from 7 degrees to 2. After that you can reduce further. Feel free to let it sit for a few weeks. Place the animal in a plastic container with a lid with some air holes. Fill it with some soil and / or leaves. Check regularly whether there is still moisture or ice in this container. At temperatures above 2 degrees, they do not go into hibernation. They will then live on their reserves. Doing nothing is not an option, I speak from experience. You can avoid these kinds of problems by keeping them fairly dry for much of the year.

    Hi guys! I’m new to this site and a new axolotl owner. I’ve had my baby (his name is toothpick) for about a month or so now. I finally got a water testing kit and I tested the perimeters earlier today. My ammonia was at 3 ppm and my nitrite was at 2 ppm. This freaked me out because I know they are supposed to be at 0 ppm. I did a water change a little bit ago and it went down to ammonia 1 ppm and in between 1-2 ppm nitrate. I change 50% of my water weekly and clean up any pieces of waste or excess food with a turkey bastwr everyday. Could this just be because the tank isn’t fully cycled yet? Should I be concerned? Toothpick hasn’t shown any signs of distress

    @Paige1warren You need to tub your axolotl and perform 100% daily water changes. Your tank is not fully cycled, and any readings of ammonia or nitrite are toxic and potentially deadly. A fully cycled tank should at all times have readings of 0ppm ammonia/0ppm nitrite/0pmm<nitrate.
