My fired bellied toad is bloated

[Classpi]

Thank you for the advice! He is still bloated and not eating ever since he was bloating, but when I cleaned his cage he turned normal, so maybe he's just shedding?
We actually have Epsom Salt, so when I get the bigger tank, which I hope I can get that tomorrow, I'll add the salt to his water and hopefully I can get a filter. Now, would it be okay if I get larger pebbles? Ones that are too big for him to acciedently eat?
Or something else that would be easy
to clean?

Glad bloating went away! Pebbles to large to eat are fine. Would not add a thick layer because dirt will get between them and will be harder to clean with gravel cleaner or similar.
