Awh, so perhaps I should not plant too many under water plants and focus on the top floating plants if CO2/O2 levels in the water drop at night.
I dunno. I never heard of that being a problem. If you have a couple/few sponge filters going in there at night it should take care of your oxygen levels. Also, I believe the floating plants are always absorbing oxygen from the water, because plants absorb oxygen through their roots, and that's the only part of the plant that's in the water on duckweed and frog bit. I would imagine most of the oxygen those plants produce is lost into the air through the tops of the leaves. In that sense aquatic plants are better for oxygen than floating plants. BTW, all of this is an educated guess based on stuff I've come to believe as true. If anyone has a scientific reason why I'm wrong please educate me.
Also -- what about the idea of having Scuds live in it as a food source, and to also keep the plants at bay?
I keep scuds in my tank. They seem to do okay-ish. They definitely cannot keep up with the plants though, they will do nothing as far as controlling growth. From what I understood they eat mostly dying or decaying plant matter anyway.
They grow and breed easily. Hopefully the salamanders would not eat ALL of them, and allow for some to live above and grow/eat off the duckweed?
Mine seems to ignore the scuds, they are too small to catch their attention. I would imagine a few get eaten here or there, but they do not actively hunt them.
Additionally -- I love your tank, but why is the water that low?
Wouldn't it be better to have a higher level of water?
It's an old tank, it has a crack in a top corner and that's as far as I can fill it. However, I like it that way because I don't have to put a lid on the tank, and there's no way an axolotl is going to jump that kind of distance out of the water. More water volume is always good, but the most important thing is floor space.
Also yes I love the natural look! Hence why I want wildtype Axolotls as well.
Wildtypes are SO underrated. I love them! The breeder gave me mine for free saying "no one likes wildtypes anyway, so just take it."
Cam -- Is your name Cameron?
If so -- That's pretty freaky!
My name is also Cameron, and after looking at the border and size of your tank, I have the exact same one I do believe.
In addition to decided to get the same style of setup, same plants, and same pets..
That all adds up to be a bit unlikely.
haha, yeah it is short for Cameron. That's a little too coincidental, eh? XD
Also, I now I am not so sure of my tank size. I remember it being 150 gallons as a child, but maybe it is only 100, or something?
What size is your tank? Did it orginally come with two fluorescent lights that doubled as lids?
Mine is only a 45 gallon, and I got it second hand, it did not come with any lights or a hood. Use this calculator to figure out your volume:

What is this plant called? the plant behind the axie of course, hehe
The plant he's on directly is java moss, the plants that are way behind him in the blurry background are naja grass.
