You have more than paddletails, there is a chinese firebelly (Hypselotriton orientalis) in there too. Very bad mix, to tell you the truth. Hypselotriton are very non-agressive newts while paddletails can be extremely territorial and deadly agressive. If something goes wrong, the chinese firebelly may be injured or killed.
Are all the 15 newts in the same tank?
They look smallish to me, and perhaps they are juveniles, but still, sooner or later, among 15 paddletails, there is going to be trouble. It´s sometimes impossible to keep two together, let alone hope for 15 to share space.
As for sexing, the male´s cloaca while engorge during the breeding season after a cold period, blue spots will appear in the tail, too.
First thank you for your response.
The pic with the chinese firebelly old,and now i have only paddle tail.
I have upload a pic of the tank,you think that it small for 15 ?
about the breeding,I need 4c temperature,can i use a container and put it in a refrigerator for a cold period.
I am really want the breed this species and i thank you for your help.
How long do you have them? Do they stay that small, or you acquired them recently?
The tank is definetely overcrowded, when they get agressive (and your animals look like juveniles, so they probably are yet to start acting so) there will be a bloodbath in your tank. The aquarium looks like it's 80cm long or so, not that big then. Especially for 15 newts...
To breed them you don't need just to put them in 4'C for a while, they need constant low temps below 15 also DURING the breeding period. Not to mention that they require water movement and a suitable spot for the female to make a nest.
I don´t mean to be cruel, but that tank is a disaster in several ways....
Way too small for 15 paddletails, no strong current, barely a hiding place, waaaaaaaay too much substrate (and a bad choice of substrate too)...That´s simply not going to work.
I honestly don´t know what to recommend....the way i see it you´ve put yourself in a very complicated situation that has no easy solution. I would separate the paddletails in smaller groups, but that can mean having 5 different containers, which probably shouldn´t be smaller than 60l each. You also need to have at the very least one decent hiding place per animal, plenty of visual barriers and a good, strong current.
The substrate is a hazard as it can be swallowed and it also looks like it´s a bit sharp. Fine sand would be a much better choice, or even better (for feeding and cleaning purposes) no substrate. Also, the substrate should be no deeper than an inch. The way you have it it´s going to cause serious trouble sooner or later as the deeper areas become anoxic and anaerobic bacteria start to flourish.
I´m sorry to be so negative, but you really need to change things.
This is probably not what you want to hear but your chances of ever breeding them are almost non-existent. Very, very few people ever succeed in getting females to lay eggs, and of those people, no more than a handful wordlwide succeed in hatching them and rearing the larvae. No one i know has ever succeeded in raising them to adulthood.
It´s a very difficult species to breed, even more so to raise succesfully. With your current situation, you can forget about it, they won´t breed.
It´s refreshing to see someone taking criticism so well. You are doing the right thing by trying to learn more about them and seeking advice. Good luck!
Make sure to check this caresheet: http://www.caudata.org/cc/species/Pachytriton/Pachytriton.shtml
You will find most information under the name Pachytriton labiatus, although that´s now an incorrect name. Your animals are probably Pachytriton granulosus, if FrogEyes drops by he may be able to give you a more definite ID.
By the way, so that not everything is so negative , the belly on one of the newts in picture 4 is absolutely stunning!
I don't think you completely understand the situation. This species is extremely aggressive to their own kind. If you keep more than a few (like, less than 5) in a tank that size, they will end up killing each other.
@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?
I have a tiger salamander and i got him as a gift , recently it looks like something has been eating at his tail! Almost like its dissolving..? Ive checked that there is no other bugs in the closure, ive also ben giving him salt baths but its inly getting worse. Sorry if its much hahaha im just super worried!
@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.
