I'm hoping to get some axolotls soon, and I've been doing as much research here as I can (there's a ton of great information!). During college I had a 10 gallon tank where I raised a blue crayfish, but he died earlier this year in the middle of a molt I'm going to hopefully get a 20 gallon long aquarium and possibly put two axolotls (once they're big enough) in there, and use my 10 gallon to raise some feeder fish that would safe for the axolotls to eat. The toughest decision that I'm facing right now would be what to use as the substrate in the tank. I want to have a planted tank, but I don't want to use sand as it may be harder to clean, and I liked the idea of putting what looked like floor tile in the bottom (I saw this somewhere on this site). I guess I'll just have to do some more browsing and see what's best!
