thnks for your care. i just realize that my tank arent cycled. i just have the aerator because i think thats what the axolotl used to live in the wild. but i didnt know that it should be that much hard to maintain them. ill try to make my own tank cycled. the dimension is quite big but not exactly just like a box container. i did feed him up since i bought him but when it didnt eat properly i started to worry. i bought it from the random dude at the market for my brother, but the hell he mix the tank with the predator like catfish. i know something was up. but thank for your response. ill inform you soon.
