It depends on the size, amount of specimens kept etc. Because of firebellies live mostly in the water, where they leave their dropping, you should at least clean it every week. Use of a waterfilter is advised to avoid a rotting smell. Frogs eat live prey, so their droppings will start to rot as soon as soon as they are excreted. Dirty water is not only bad for the frog (causes eye and skin infections), but is also dangeropus for the owner!
daily
once or twice a week
They won't harm humans, though you should wash your hands after you handle them. This is mainly because they carry bacteria. They do emit toxins that will harm other fish and amphibians in the same cage.
I dont have a clue!
every 4 days
Of course it's fine! You just need to clean out the cage more often.
Every 1-2 months.
SAME size fire belly toads. If they arent same size they could get cage territorial and kill eachother, so make sure they are the same size OR around the same size, but have a big cage..mine, Violot, lives in a fish tank its BIG and she loves it and im getting her a friend frog today..he might be more than a friend though..idk. Hope I helped!!
about once a week works for me and my friends that have tortoises
Just keep the cage clean. and clean it like u would clean a fish tank.
it is unhealthy so you should often clean the cage.
You should clean your hamster's cage every couple of days. PetProductsByRoyal.com
