Hi all,

I have 8 P. Waltl larvae which are just over 2 weeks old. They are approximately 1.5 cm long and are feeding on small white worms. This morning, I noticed that one of the larva was hanging out between the aquarium glass and the ammonia sensor, so I took the opportunity to take some macro shots. Much to my surprise, I managed to capture a short video of his 3-chambered heart beating! You can also see his intestines full of white worms.. ;) Here's a link to the video, in case anyone is interested: Spanish Ribbed Newt larva's heart beating - YouTube

    Try various foods to mimic a natural diet. If your worms are dead, try living things for sure. My newts prefer live food almost exclusively. My eastern newts eat snails, black worms, baby brine and others. They are like picky children. Maybe blood worms are their broccoli lol

    Hey there guys! My tank is cycled but I'm still battling ammonia spikes just when I get it down to zero. I keep the tank clean and do water changes when needed to lower it. Ammonia is about .25-.5 right now, 0 nitrite, 20 nitrate ppm. Not sure why two months in now it's still fluctuating?

    @axolotl nerd, rads, the cycle has crashed or the tank wasnt fully cycled to start with. Remove the animals to a seperate tank or tub, give 100% daily water changes. It can take a while to cycle a tank if its yr first time.

    Hey guys! We had our first unexpected hot day and I was an idiot and forgot to put on the fan for my axolotl tank. When I came to feed her at around 7, I noticed the tank was 75 degrees!! It has never been this warm, it’s always a stable 67ish without a fan. It was only this warm for today (yesterday it was normal temps), and I immeditately got the fan on when I saw. It is down to 69 degrees now. Is my axie going to be ok with the increase in temperature for a day?
