It’s very dry in Colorado. I make sure to spritz every night so while I’m sleeping. I have a nifty hydrometer that I got from Walmart. It tells me blue, green, red; too little humid, good, too much respectively. It’s been helpful to me.
Hey y'all, recently my juvenile axolotl's tail has been floating and can swim down but his tail lifts to an angle and I believe that it is stressing him out. He gets in between his plants to balance himself and I am cleaning out the bottom of the tank with my baster. I believe I overfed him and he also may have eaten many air bubbles. He's been like this for nearly 1 1/2 days.
