When did you add the rock? Has your tank completed nitrogen cycle yet? You might be okay with hardy fish for now in a larger tank like yours, but you are setting yourself up for likely bad results if you add livestock too fast after setting up the tank. I'm not here looking forward to a "told you so" moment, but you might consider more research to avoid failures and unnecessary loss of life.
Did you add any seeding bacteria or true live rock in your tank?
I read your other thread and your response about your interactions on other sites when advice was given, but you may not realize how pretentious you might seem or why people might caution you against your approach since it seems to follow many paths on which many have failed.
The main advice I would give right now is to be patient, do not rush things, consider advice from those with experience, do more research, and do not think you are smarter than almost everyone else and will come up with a "new", cheap way to the most beautiful and colorful tank that negates the need for any of the equipment that others spend money on. I doubt many people are buying the equipment simply because they have a bunch of money to waste. If you choose a different path, that is up to you, but research the reasons for the equipment before dismissing it as rich-folk money-wasters.
I only offer this advice in the hope it can help prevent failure.
By the way, your axolotls look great. I had one for about 5 years. How long have you had yours? Did you raise them from babies or buy adults?
The Tokay gecko looks quite emaciated. I hope your care for her helps restore her health. I never had a Tokay gecko, but I have kept many different lizards and geckoes over the years and currently have bearded dragons.
