A little background info- I have 2 beautiful bettas named Serena & Blair (I love Gossip Girl, hah!). They used to live in the same tank but Blair started becoming aggressive towards Serena and ended up biting 2/3 of Serena's fins off. I could tell Serena was having a hard time swimming so I moved her to her own tank/bowl and since then she has been doing great. For a few days she didn't have an appetite, but now.. that girl can eat! She knows when I'm feeding her and sits at the top and waits. She is also very playful, she will follow my finger as well as me when I walk across the room. Blair is doing fine too- she seemed a little sad once Serena left (because she had no one to pick on!) but she eats alot and is playful as well.
Serena's fins are started to grow back marvelously. I'm amazed at how fast they are coming in- they are coming in clear though (she's a pretty reddish/pink color). BUT the one thing I've noticed twice is this weird "ball" that is attached to her underside by a THIN string of something- the string is barely visible it's so thin. This thing is really hard to explain- the middle of it is see through and looks like it has a squiggly line in it or something. The first time this happened it fell off, & I changed the water yesterday and it showed up today. I used that stuff to make tap water safe for bettas so I'm not quite sure what it is. It's very strange looking, I took a picture and it's not too good of quality but maybe you can see what I'm talking about.. Does anyone know what this weird thing is?!
