i found a forum kinda like pet talk, except just for axolotls and salamanders etc. they have really helped. i just bought a new filter, apparentely undergravel isnt that good, and an ammonia tester. i got rid of all the gravel, cause they can swallow it. i have completely cleaned the tank. phew i have done almost everything possible. Even if scarlett doesn't survive, olive, the other girl will definitely have a long and happy life because of all the new things i have learned.
