For some reason whenever i change out the water for the newt larvae they end up dying the next day. They're kept in plastic deli cups with lids. I try to leave about 1/2 of the original water in their cups and add new water but they still end up dying. I generally would change the water if its really gross looking like if its murky or just really green. But I'm starting to think they've become more accustomed to being in the dirty water. So i just stopped changing it all together and now i just use a pipette to suck out their waste but since I've been doing that the water has gotten really low in some of the cups. Any suggestions?

What species are they? Do you check the water you put in? Do you do chlorinate it? Maybe try keeping them in larger containers with smaller water changes percentage wise.

They're striped newts. There's a system where we have a filter on the sink water so I'm assuming there's no chlorine in it

How big are the deli cups and are you using dechlorinator in the new water BEFORE you add it to the deli cup?

I just read a care sheet for marbled newts and it said not to change too much water for larva because it will kill them. In fact it recommended exactly what you're doing -- remove the waste with a pipette and change very small amounts (10-20%) of water at a time.

Here's that link and excerpt: Triturus marmoratus | Care-sheet | Salamanderland

"During the first month of life, scrupulous hygiene must be maintained, eliminating waste and excrement with a syringe, making minimal partial changes of water (about 10% -20%). Total water changes that would cause the death of the larvae from osmotic/chemical stress should be avoided."

I've never raised baby newts but have kept fish for decades and adult newts for several years. Large water changes can be dangerous because they can change the water chemistry too quickly.

Good luck!

Filters do not remove chlorine. You need to remove chlorine with a dechlorinator.

I've tried raising newt larva individually in deli cups too, with mixed results. I got much better survival rates when I started keeping groups of them in ten gallon tanks with sponge filters. The only drawback to this that I've found is the risk of cannibalism, which can be minimized by keeping size classes separately, and keeping them well fed.
I was initially concerned about water changes myself, however by using prime, and changing no more than about a third of the water each time, I have yet to lose one- but occasionally, one may find itself being sucked up into the siphon.
If you find that you simply must raise them in a deli cup, you could minimize your losses by using water from a well cycled aquarium, rather than tap water.

    @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.

    Hi! I have recently gotten a spotted salamander. Did some research and found lots of info, but just wondering if they brumate in captivity! Thank you to anyone who can answer this ☺

    @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.
