Betta’s Tail Has Lumps?

Leo has had these lumps for a really long time.

He had tail rot as a baby (got him at 3months), and was treated with Betta fix for a long time (it wouldn’t go away).

He’s had these lumps on his tail for a long time, I thought they were just folds but now that he’s full grown you can see them easier.

They don’t seem to effect him, his tail has continued to grow, he’s still playful (he comes when you call his name, super cute), and he eats normal.

The blue started showing up when we moved across the US (he traveled in a half gallon between my feet, we did it straight shot, left at night and arrived the next night). So I’m not sure what that is either but since he acts healthy I assumed it was part of him maturing or caused by stress (we moved when he was 8 months old).

He’s very in touch his his feminine side and will show us his stripes when stressed (and doesn’t do much flaring) so I don’t think it’s hurting him.

(He’s a crown tail, but the fin rot has prevented it from being all that obvious.)

 

The lumps are from the fin rot he had in the past, and they won't go away. think of fin rot as a scar. The blue you are seeing could result from a marble gene which causes betta to go through a color shift in their life time. However, most likely this color and pattern resulted from different lighting and better health. You were also lied to as him being a crowntail betta. You actually have a delta tail with a bit of rosetail in him. And I wouldn't call stress stripes being part of his femine side. Females betta stripes go in a different direction than stress stripes.

Ok, then being scars makes a lot of sense! Thank you!

I’ve always been told that showing stress stipes is more of a female Betta thing, but I guess not! (He hasn’t shown them since the move.)

Both are plausible for the cause of the blue, when he moved his lighting changed a little because he’s now by a window of an apartment vs being in a darker area of a dorm with just his light strip.

Oh, I’ve always thought he was a crown tail! It’s cool he’s a delta! He had little clear spikes on his fins as a baby, and he has the crown tail look on his dorsal fin. So I always thought the fin rot was the reason he looked funny (for a crowntail). I got him as a blind grab. All I was told was that he was male. (Here’s a semi-blurry photo of him as a baby a few weeks after I got him, he was super tiny. And was originally all pink! This was once I noticed he had turned more red-ish.)

 

The spikes I see in the baby picture are from damage most likely from other bettas. He probably also has a fringe gene which breeders like me hate. Fringe decreases the value of a betta and makes them more prone to rot.

Oh! Ok thank you! Luckily I got him just to be my dorm buddy (now he’s a spoiled family pet) so if he has bad genetics it doesn’t bug me and they won’t be passed on.
