Small species of worms and nematodes

Doesn't newly hatched small newts like c.o. take white worms? White worms are about 1mm long right?
Why use grindals or micros?

I was also wondering about the use of C.elegans as food for larvae? It's a free-living nematode of about 1mm...

Jesper,
Baby whiteworms may be that small but adult whiteworms are bigger than 1 mm...

Ah, yes thought it was funny that they should be so small... Found another source stating that they become 2,5cm big....

Grindals become about 1.25 cm, microworms 1-2mm...correct?
I am a little bit interested in what is used to feed larvae, from hatching to morph.

I've raised my first batch on bbs(artemia) the first week and then small copepods. I could probably start them directly on small copepods..
So if I would like to replace with worms, do I need several types or is one type or worms ok?
Say grindals all the way?

Anyway I'm interested in what you personally use to raise your larvae(depends on size I know but...).

You can use white worms or grindal worms once larvae hit about 18 mm; less if you use the smaller worms in the culture. Microworms are a first food. I'm using microworms to supplement my low Daphnia numbers.

Isn't it a pain feeding Daphnia to small larvae?
I suppose you have too get newly hatched daphnia for larvae, mine still can't eat Daphnia(magna..)(they try though

) or are you a Moina man?

Guess I'll have to go for microworms then. It must mean a lot of work finding the small worms in a white worm colony....

So John, what do you think about trying to feed C.elegans?

With Daphnia you put the adults in the larva tank a few days before feeding begins and the adult Daphnia produce young over the following days. Just add more every day or so. Easy peezy

Small worms in a white worm colony, well, I just put a pile in and probably 50% in a growing population are under 1 cm long. The larger ones make for interesting entertainment - like a man trying to swallow an anaconda...

C.elegans? Rings a bell, but species name is totally unhelpful without the genus name. It makes me so mad that people quote "T. bla" and "C. whatever". On the first mention of a species name you should include the genus. Only after the genus has been mentioned once can you use the abbreviation of the genus name :p.

You should know what C.elegans is John....

It is quite famous in the scientific(biology/bioscience) community.
Everybody just refers to it as C.elegans, so I assumed you knew what I meant.

White worms do indeed get past 1mm in length, although they are about 1mm in width/diameter.

Grindals are often used with larvae because of their size, but also their reproduction rate is much faster than that of white worms. There's a few good pages by the Bug Farm (http://www.livefoodcultures.com/) about the differences between grindals and white worms.

If you're raising c.orientalis from larvae to metamorphosed juveniles, there's discussion about how the red belly colour of cynops requires other types of food besides white worms. (Talk to Nate and Jen.)

I'm a big fan of white worms, I usually gutload the worms with fish flakes for 24hrs before feeding to my animals. They're easy to care for and quite sturdy if you don't heat them past 80F. They also survive a few days in the water with no problems.

When I was breeding Notopthalmus, Cynops cyanureus, and Pseudobranchus axantha at work, I just chopped blackworms or sorted them quickly for small individuals.

Yeah, wish I could get blackworms...
On the other hand my goal is breeding all my newt food myself and I heard that blackworms reproduce quite slowly eh?

Its not worth the time and effort for me as I can buy .25 lbs (.11 kgs) of blackworms for $6.99 (I don't know the current conversion rate for Euros) locally.

Blackworms are not available here, I think one online store in the UK have them that's about it.

Hi Jesper

The first batches of larvae I successfully raised I fed small Daphnia and introduced Grindal worms after the first couple of weeks.

The larvae I have at the moment have been on Grindal worms from the outset plus a few tiny bloodworms that came in the bags.

I do have Moina culturing but not enough to feed to the larvae yet. Plus I am finding it interesting seeing how light these larvae are in comparison to the ones that were fed on Daphnia.

My C. o were raised on daphnia and microworms. The microworms worked well except that if you fed to many into one spot it apparently annoyed the larvae. It takes a while for them to grow out of microworms and some will still take them even with all four legs. The only annoying thing is that microworm cultures require lots of attending to to keep running as you need to set up new cultures regularly. I've almost lost mine a few times when I forgot to set a new culture before going on a trip of when one crashes. Thats why its important to have at least 2 running at one time(i usually have 3) of different ages.

BTw, my biggest larvae is showing some adult like characteristics...Whoot!

    I do not have my Axolotl’s yet waiting for my cycle to complete! I am towards the end of my 30g fishless cycle. It has been a long journey. I have easily been processing 4ppm of ammonia in 24 hours for about a week.Each night I add 4ppm ammonia ( Dr Tims) and test every 12 hrs and nitrites read around 2ppm but when I test after 24hrs they are at 0 nitrites. I am using API master Kit. Should nitrites be constantly 0 in a 24 hour period or is a spike 12 hours later normal? Is my tank cycled? PH- is 7.4 Nitrates- 40ppm and will do water change once I am sure tank is cycled

    Hi guys! I just have a quick question regarding axoltols. I’ve had my lotl since October and she is a year old now! Anyways, her water has been on the warmer side of the spectrum (about 69-70 degrees F, 20ish C). I finally got a fan to blow over the top of the tank, and it decreased to about 64 f in 2 hours. Super happy to be able to keep the water cooler, but I was wondering if axoltols have any reaction to the water suddenly becoming cold? Should I lower the temp more slowly? My lotl isn’t acting stressed or anything, but I just want to make sure there won’t be any problems. Thanks!

    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 )

    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
