It keeps coming up!
I agree that the stone thing needs to be changed, and quickly. I posted these suggestions on another forum as a guide to figuring out a tank, going from what I'd experienced (I hereby disclaim I've had axies for a year, including having three happily living in a 45cm tank for approximately 5 months due to the Australian summer, and I have been reading and talking my butt off about them

I further disclaim that it is my intention to have axies and keep them in the best conditions I can until I die/merge my consciousness with the internet) :
1. Can they swim around, turn around easily, go up for air, have plenty of walking area?
2. Can they hide if they get peeved off with someone?
3. Can the filter hold the biological load of the tank and are you comfortable you will be able to do the water changes religiously? (I'd put for this one, that for an axie, you'll need to change a gallon of water out a day...?)
If the answer is yes to all three questions, you're good. Then ask:
4. Can I afford the space for a bigger tank?
5. Can I afford the cash for a bigger tank?
If the answer is yes to 4, then you get a bigger tank (Even if it means a few weeks in a big bucket or a holiday in the fridge whilst you save religiously).
It's interesting just how confronting people feel they have to be on this issue. I really hope that we can get to the point where we go; "Good start, now what you'll need to watch is:---------, and to do that you do --------, and if something goes wrong, don't panic, you need to---------. and then, When you've got the chance/space, you can get a larger tank". Providing support for new owners will give them a thirst to come deeper into the hobby, to become more complex with their habitats and to promote better husbandry practices with everyone they meet, and that can only be good!
Although, I still think yelping at the sight of gravel is justified
