One of our axies has had lump for about 4 months now, it started out as a small, red patch but is now a sizeable, raised patch of bumps. Our PH was sitting around 6.8 so thought that might the culprit, been adding bicarb at water changes to raise it and it now sits around 7.2. GH & KH were also low, both around 3 so raised those, both are now around 8 and have been since mid January. The photos were taken at the beginning of Feb and I think I've seen a small improvement since then. We've had some tiny (1-3mm) creatures on the glass, could they be the cause and does anyone know what they are? I've been crushing them daily and they make a crunch. Our other axolotl hasn't had any issues. Here are the parameters from the last water change and is the norm for the tank: 12 Feb, PH 7.2, GH 8, KH 8-9, Ammonia 0, Nitrite 0, Nitrate 15, Temp 19C.

Would also appreciate a gender check on the leucistic. Can take more photos if need be, any help much appreciated, thanks!

It's not something I'm familiar with.
I guess it could be bacterial (like a swollen infection), but I'm guessing it's more tumor-like in origin.
If you can, might want to discuss it with a vet.

I very much doubt it's caused by any water issues, since your parameters are close to perfect and the axolotls look otherwise healthy.


The creatures on the glass are freshwater limpets, a common hitchhiker on rocks and plants from aquarium stores. They're completely harmless and won't get very big. A sudden population explosion can be a sign that you need to clean left-over food and poop more, but you'll probably always have a few around from now on. They're very difficult to get rid of (but also harmless, so maybe not worth the effort).


Gender check depends on the age. If the leucistic is more than 1.5 years old, it's definitely a female. If less, could still be a late-blooming male.

Thanks so much Murk, you were a great help to me once before as well. Am overdue taking her to the vet but certainly will.

Thoughts on it possibly being fungal? I've let the tank get to 22C at times but no higher. She did develop typical, fluffy fungus on a gill that went away when the temp came back down but I've never seen a fungus like this before on an axolotl.

Glad to finally know what they are. The limpets did indeed appear after bringing home anubis.

Not sure on age but feel she's just reached full length, so maybe a year old? Definately more elongated than my other girl who is older and plumper. I too think the genitalia is still within reason for female but guess we'll see if it gets any bigger.

I would be very surprised if it's fungal, but I'm not a vet and my experience with disease is limited.

For treatment or medication I really do not know enough, I'm afraid.
The search function of the forums leads to a few possibly similar cases, but nothing conclusive that I can find.

All good, you were a great help. When I do take her to the vet I'll post the results, incase anyone has a similar issue

    Also, she was fine at the higher temperature. Perfectly healthy and never showed signs of de stress. Just thought it being colder would make her happier and digest a little slower! (She’s a pig :p )

    @Paige1warren That should be fine. I wouldn't suddenly put her in very cold water without acclimatisation, but a few degrees over the course of two hours shouldn't be a problem at all.

    I have had my 2 axolotls since June 2020 and I had hoped they would mature the same gender but unfortunately they are not. I am currently on vacation and planned to separate them once I returned, my axolotls are currently being cared for by a friend who knows the basics to care for them properly. A melanoid and a leucistic. I had a feeling but didn't prioritize it enough and now I have many many eggs in the tank with both of my axolotls. I have zero experience with eggs and cannot really care for juvenile axolotls but I really DO NOT want to kill them. What should I do? Are my axolotls okay being in the same tank with them? would the eggs be okay all together in a tank by themselves? Where can I find someone to care for them and hatch them?I'm so stressed and worried I just want the best for them all.

  • axie owner:
    you are going to have to get a bucket and put the eggs in that. they can hatch anytime between 11 and 20 days. order in brine shrimp eggs and get your friend to watch a video on hatching them. make sure your friend does 100% water changes every day. keep the water around 64digres and make sure your friend sends daily updates on them. i found kitchen salt works for the brine shrimp eggs. hope this helps.

    Hi guys.. I might of made an error and need some advice. One of the hides in my tank is too small for my axie now, but I did not want to buy another hide because they are expensive, so I decided to DIY one. I used a Tupperware (cut into a little home) and glued rocks from outside and plants on it. The problem is, I washed the rocks with soap and hot water. I completely wasn’t thinking. When I washed them there was no soap residue that was visible on the rocks, and the rocks have been drying for 3 days on the container. So it has been 3 days since I washed them. I used aquarium safe silicone to glue them on. It was fully dry tonight so I decided to put it in my tank. I had it in for about 3 mins until I realized j had washed the rocks in soap, and I took it out immediately. Should I be worried??? I’m really freaking out, I don’t want anything to happen to my baby! I was truly not thinking. I also read that it was safe to use rocks from outside, but now I’m not sure? Can anyone help

    @Paige1warren, Since you took it out straight away it should be ok but I'd still be doing a big water change. When I was a teen, I took some rocks from outside, washed them (probably in soap) and put them in my turtle tank. He died a week or so later and I've never used any rocks from the garden since because you just don't know what's been on them, such as pesticide and I suppose the mineral composition of the rock comes in to play too. Letting them dry for a few days before adding them also would have helped so you should be fine

    @Saturn, okay, thank you so much! Firstly, I’m so sorry about your turtle :(. My lotl seems to be fine, I haven’t noticed any changes or signs of destress. I do 25% weekly water changes (I have a fully cycled tank), but I will do a 50% change today. I hope that everything turns out fine. Axies are pretty good at showing they are not well or stressed so I’m hoping that I got the rocks out fast enough. Thank you again!

    Can't say if this is what's being referred to, but I had some ceramic tiles in an aquarium for a while. I used a silicone sealant to secure them to the bottom and to each other. It worked well for about 6 months, but eventually a little water got through my imperfect seal and started creating mold problems
