Hi, everyone!

I have 2 axolotls: one is a wild-type (8 inches) and the other is a melanoid (7 inches). I bought them 5 months ago, so I am unsure if they are now adults/sexually mature. Could you please tell me if they are male/female?

Also, they are currently in separate bare-bottom tanks, but I would like to house them together soon. The family I got them from keeps 3 adults in a 20-gallon long tank. Should I put mine in a 20-gallon as well? And how much sand would I need at the bottom?

Thank you so much! 😊

Difficult to tell with the photos.
Have a look to this page :
Unfortunately, a well diagnosed male is definitively male, but you'll be sure of a female only once she has laid eggs.

Thanks for the link! So I’ll know if I have a female if I see eggs after putting them together, correct?

Do you have any recommendations about tank size and decor for them?
 
a twenty gallon tank is the minimum size tank for one axolotl (used to be ten gallon years ago with thirty being widely accepted now) with ten gallon being added for each additional axolotl.
sand is fine to be used in an axolotl tank provided it has been thoroughly cleaned before hand and that it is turned over regularly to release any debris and gasses.

And nowadays.
Debris accumulate sometimes when some plants decay in autumn. Need some superficial cleaning but nothing dangerous for well-fed axolotls kept at adequate temperatures.

Your tank is so nice! I am assuming it is a 40 gallon? What kind of plants do you have in there? Do you use a filter?
 
I have no filter.
pH is between 7,0 and 7,5 : ammonium is not dangerous at this values and most aquatic plants prefer uptaking this nitrogen form.
In France, noone among my friend use a filter for axolotls.

I chosed to mix diverse plants to manage nitrogen and O2/CO2 :
- Bacopa amplexicaulis as a partially emerged plant, efficient in uptaking nitrogen, with unlimited atmospheric CO2,
- Salvinia natans as floating plant. I have also a few Lemna minor which never grow much because nitrate levels are always low (about 5 ppm). Lemna minor is a good indicator : if it starts covering the surface, there is something wrong.
- I have also Riccia fluitans. Also a good competitor versus Lemna minor.
- I introduced Egeria densa 3 years ago but it was outcompeted by Bacopa amplexicaulis. I introduced Ceratophyllum demersum last year after clearing part of the Bacopas.

My aquarium is in my garage (north), with seasonal temperature variations : between 8°C in winter and 20°C in summer (extremes : 4°C - 22°C). The tank is open, so water temperature often 2°C below air temperature.
And, of course, I have a light for the plants. Axolotls can hide in the plants or the wooden pieces.

Live food as often as possible because I noticed pellets pollute the water (they probably contain compounds useful tu form the pellet, but not digested by axolotls).
 
Thanks for this info. This is very helpful!
 
I made my technical choices which work well in my conditions.
Seek for other testimonies. You'll sure find other options which also work well.

    Hey everyone, just want a little advice. Its 55 - 60 celcius in my Salamanders tank. Hes curled up and tyring ti bury himself, Im assuming hes too cold. I was wondering if he would benefit from a heated rock cave (since he LOVES his cave) that I could set on low? I NEVER see him curled up and trying to bury himself unless his tank sits at 63 degrees celcius or lower. So I am assuming hes a little uncomfortable.

    He also seems a little sluggish, again, assuming hes cold. Having heating trouble with the new house right now. What do we think? Was thinking of grabbing this for him since its got very low, medium, and higher medium heat settings that exude heat downward inside the rock cave but ALSO exudes it UPWARDS outside of the rock cave, effectively keeping the tank itself a little warm. Seems like it miiiight be a little small for him though, my guy is about 7 inches from tip of his nose tothe tip of his tail. What do we think? https://www.amazon.com/Reptile-Simulation-Adjustable-Temperature-Tortoise/dp/B0CH1DPGBC

    Had a question that I just want to be sure of. My marbled newt is a little over a year old and has started to develop and I noticed that he is starting to swell a little below his abdomen. I guess I’d like to know if they are his testes or if I need to be concerned.

    Hello!!! I'm new to this website and idk how to ask a proper question on the designated spot yet, so I'll ask here, I'm a first time Axolotl owner, and my dad used to run an aquarium store, anyways... Orca, my Axolotl, seems to loose parts of her toes on one limb from time to time, I can't seem to find the problem. Tempature is well, she doesn't seem to have any infections or anything, though. And I'm not sure if I'll be able to find a vet in Brazil for amphibians that are in a reasonable distance to drive without stressing Orca out too much

    Hello, I’m hoping for some advice please. Our Axolotl is about 7 months old. Till now no problem. Eating, growing and happy. He’s simply stopped eating. Everything looks fine, his gills look healthy and no apparent signs of sickness. He just swims past the pellets and bloodworm like he can’t smell it. I don’t think it’s a blockage either. Any ideas and suggestions for treatment would be much appreciated. Thank you!
