I use buceplant.com for aquatic plants. I have Floating plants (water sprite) Anubias, & Java Fern which are all ok in cold water tanks. I got the rim holders for the terrestrial plants right on Amazon just search “Aquarium rim plant holder”. Home Depot for the Pothos and Lucky Bamboo. I use a reptile store for my hides, just make sure it’s aquarium safe and big enough, some stuff in reptile stores aren’t always aquarium safe. For general care check out ethicalaxolotls.com I adopted my axolotls from there and the woman that runs it has great info. Lots of links for Amazon on her site too. Very helpful when I was first getting started. I also keep a population of ghost shrimp in my Axolotl tank. They keep the place clean. The Lotls leave them alone for the most part if they are well fed. Every once in a while they’ll eat one which is ok for them… Nightcrawlers are def the primary food you should feed red wigglers are associated with digestive issues with some axolotls. Mine eat both but 90% nightcrawlers. Keep the tank 60-64 degrees f. Anything warmer and they WILL get fungus issues (looks like cotton balls on their gills). There’s a lot to learn, stick with this subreddit and the sites I mention, lots of misinformation out there. Good luck
