No, scales won't fall because of that. :\ He should be able to reach his tail, it's long enough.

maybe he's trying to bite his tail? I don't know him as a tail-biter, though.

Missing Scales? These symptoms don't make sense or add up at all... :\

np. his poo seems regular, but I see some scale loss near the anal fin

Aw... Thanks. :3 I'm afraid that if there is no external problems, then he might have internal parasites. How's his poo?

Jhghi!!!

EDIT: King Dedede is doing this and I don't wanna get insults again so im asking someone i trust.

Parasites. Anything that can irritate his external body.

do you know why a betta would be lethargic then suddenly swim around in jerky movements?

Why?! Don't you care about Dedede or was it before he went lethargic?! Sorry, but I'm blunt when it comes to Bettas is sickness. :( ~LTB

I mean $20, my mom said she already gave but I spent it on something else. ; ;
