Hi, I'm a new axolotl owner and I need urgent help with my tank.

I've had Mizu (my leucistic axolotl) for roughly 2 months now, and I'm really concerned about the state of my tank. It's a 20 gallon tank, with very fine white sand as substrate, three natural plants. a cave as a hide and an air stone. It has installed a backpack filter (https://www.amazon.com/Fluval-14001...rds=fluval+c2&qid=1551817038&s=gateway&sr=8-1) set on low to minimize the flow and also a couple of fans to keep it cool (always under 68 °F if possible).
Mizu has been growing non-stop since I brought him home, eating an earthworm and some axolotl pellets everyday since it's still pretty young, and as far as I'm concerned it looks very happy and healthy in his new house.

But the problem isn't Mizu's health, the problem is the tank. I've had some issues ever since i set it up, having to wait sometime for the substrate to set on the bottom when filing it with water, or reducing even more the flow by attaching a sponge into the filter exit because it was disturbing my axolotl. But now those problems seem to be solved.

What isn't solved, and matter of fact is becoming worse, is the algae on the tank. It started to appear the first weeks, attaching to the plants, the cave and also the walls of the aquarium, but at first I thought I had it under control. The water was crystal clear, and a 20% water change every week and some scrapping on the glass looked like a fine solution. But I was wrong! The algae, that I don't even now if it's algae and what type it could be (very fine white filaments that attach to everything), has been growing and growing, and now it's out of control. The water has become very cloudy and I don't know if that's also an algae thing.

Mizu looks fine by now, but I'm concerned, not only about the looks of the tank, but also about the axolotl's health. I always add the water to the tank treated, and I cycled the aquarium with SERA biostart before introducing Mizu. I clean all the poop as soon as i see it and never leave any food that hasn't been eaten. I even control the amount of light that the tank gets to try to stop algae from appearing.

I don't know what else to do, and I'm starting to get worried. Is there any solution to the problem, or have I been doing something wrong? Any help would be much appreciated.

One last thing, sorry for my bad English (I'm from Spain) and also I think it's important to say that I don't have any kind of experience with aquatic pets or aquariums maintenance at all.

:)

Can you attach a photo of the tank, especially the algae? And what are your water parameters?
Is the tank near a window? Algae will go crazy in natural light, I have to scrub my outdoor turtle tank weekly because of the algae.
The cloudy tank may be from the algae, but it may also be a bacterial bloom. This can happen and does sort itself out, with weekly water changes as you are doing.
What kind of live plants are in the tank? If you can also attach a pic of Mizu as well it might help.

Hi Hayley!

Ok, I will attach some photos. About the parameters I haven't checked them, should I buy some water tests?

The tank is near the window of my room, but I keep it dark most of the day since I'm at university all morning and I don't get much light in the evening.

Regarding the plants, there's an Elodea, a Ceratophyllum demersum and another one that I couldn't identify but it's shown in the pictures.

Thanks for the help!

I'm sorry I can't help with the algae I've never seen that before.
However I can recommend that you get a test kit I like API freshwater test kithttps://www.amazon.com/dp/B000255NCI/ref=cm_sw_r_cp_apa_i_1MCGCbGDBR91S

Knowing the parameters of your tank will help you solve lots of problems and manage your axolotls health

Is your tank cycled? Tank cycling is an important part of making an axolotl home that many beginners don't know about.
Here is a guide to the nitrogen cycle that I like I'm sorry I only have one in English.

Good luck with your very cute axolotl!

We’ve had cloudy tank and algae issues in the past and discovered our filter wasn’t working properly..... The water was being sucked up fine, but then overflowing inside and going back into the tank without being filtered.... might be worth checking that out.
Draping a towel to completely cover the tank for 2 or 3 days can help too - the algae all comes together to become something that can be sucked up into the filter or scooped out with a net.... There are also commercial water treatments you can buy too...

The cloudy water looks like it could be a bacterial bloom but the white algae stuff has me stumped. I would have thought spermatophores but it doesn't look like other pictures I have seen. If it is algae I wonder if it might have been brought in by the plants. Another idea is maybe it's fungus? When I was setting up a betta/planted tank the wood I put in grew a layer of fungus which eventually went, though it didn't have the same structure as this and I'm not sure what the source would have been in your tank.

Thanks Giuseppe! :)
I'll definitely get some freshwater tests to know what's wrong with the water in my tank.
I want to believe that the tank is cycled, since I added some bacteria from a starter kit, plants from already cycled tanks and I've been doing regular water changes and tank maintenance in general, however I'll know for sure once I test the water and keep an eye on the parameters.
For now the water seems to be more clear and the constant scrapping of algae from the glass looks like it's working.
I'll surely post an update once the problem has been solved or I have tested the water and found the cause of the mess!

Thank you so much MrsAJ! since your answer I cleaned the filter to make sure it was working properly, replaced some components that were already "worn-out" I guess, and I've kept the tank covered with a towel for two days.
Everything is much clearer now, and algae doesn't seem to be growing as much once I remove it. I'll keep doing some cleaning and water changes and hopefully everything will finally come back to normal :)

    Hi I recently rescued a lotl (i did weeks of research before rescuing) Hes mabey 5 or 6 years of age..the previous owner could not remember the exact age of him. I got him from her as he was or had been picked on by his tank mate another lotl who was bough with him from every younger age, I noticed one of his gills, a middle one at the end had split in two? And is slightly more floppy? He also appears or mabey I'm just over worried to mabey have lost some feathers, is that normal to lose some?...all levels in the tank are fine, but wondered if theres and advice anyone could give me as an experienced owner to a new one.

  • Axolotl Queen:
    @Lanalotl Sounds like the gills may have been nipped by the tank mate. If he is in his own tank and the parameters etc are all good, then he should grow them back and they should go back to full health and strength. However, depending on how old the injury is they may not fully grow back if they have been constantly nipped at.

    Can anyone tell me why this is happening? We just did a water change and after freaking out and whipping around the tank, an hour later they look like this. It won't let me send a pic. The edges of their gills are white and it looks like they have skin shedding off

    It sounds like something went wrong with the water change, so this could be very dangerous. Did you use a dechlorinator? Could it be there are traces of chlorine or soap in the water? (Or for example, in the bucket you used?)

    Unlike
  • Murk:
    Normally, I would recommend taking them out of the tank asap and putting them in a tub with fresh water, but if there's something wrong with your tap water or dechlorinator, that might not help either. Do you have acces to bottled water or rain water?

    I think my axie is dying, he’s never had any issues before, I’ve had him 3 years, today I noticed some fluffy looking stuff coming from his genital area so I took him out of his tank and did a full tank clean to make sure the water wasn’t infected as I thought it was fungus and then I noticed he had a cut on his belly which was only small about 5 hours ago and now it’s spread to all of his belly, what do I do I’m freaking out

    Hi I have 2 4in juveniles (I’ve had them about 2 weeks and they are doing well I think they’ve grown a little already honestly) but I am supposed to go on a 5-6 day vacation in October about 3-4 months from now. I am wondering how I should go about their care when I am gone. I thought about putting them in separate (fairly big) containers with live plants and/or bubblers with a fan in the dark and either fridging them (my last plan) but I am hoping to to either have someone I trust come feed them and turkey baste waste out or just leave them out and clean the containers before we leave and have someone come check on them once or twice. Does any of this sound like a good or bad idea? I want the best for them. All help appreciated :)

    Could be he's just excited, spooked or temporarily stressed, which could pass in a few hours. It could also be an indicator of other problems. Do you have any recent water parameters?

    Help! I got my first axolotl two days ago and they have stopped eating. They ate a few frozen blood worms the first day and haven’t eaten or been interested in food since. I feed them frozen blood worms and the tank is around 64 degrees. I do have a filter that moves sometimes and I noticed them swimming up to it, I have a new filter and a fan coming today or tomorrow. I leave the worms in the tank or a little bit before taking them out so I don’t know if they ate when I wasn’t looking. I know it takes a while for them to digest. Does anyone have any tips or knowledge they can share? The pet store I bought them from didn’t have gravel or sand in the tank so I’m not sure if theres an issue or if I’m just impatient. Thank you!

    @MuggleMiChu I would say try live black/blood worms untell they are full or just turn there head away ( that's what mine do) if that does not work try to get some live brine shrimp and see if they eat that. baby axolotl prefer live food over frozen food as the frozen food is too cold for them or they can't eat it in one go( that's if you do the blocks) mine eat chopped up frozen thawed shrimp. as for them not eating from what I have experienced with my second axolotl, I got her when she was about an inch long and she ate every day, when they start getting 3-4 inches long they will gradually slow down there eating. and if you really want to do substrate I would do sand because if they do ingest a little bit it won't hurt them.
