What do they look like? I think my boy might have them, but it could be tail-rot too.
I'll post pics after my class *runs*
Edit: Attached a pic of the end of his tail, and the way the tank was set up before today. I just noticed it this morning, he was fine last night

I also removed the large branching plant thingy from his tank, incase it was the attached plants on it that were causing the damage. I've got him in his original container now (he's a WalMart rescue, lol)
I named him Sushi, lol. I added a couple of drops of BettaFix to the container, and changed the filter in the tank, as it was time for that anyways.
Water temp in the tank ranges from 80 to 84, and I use Jungle Start Right with Allantoin, which makes the
ammonia,
nitrate, and
nitrite levels all safe. I change probably 50% of the water as well. Tank size is 5 gallons.
The reason I'm asking is because I left the dorm room yesterday at 9 am, and didn't get back until 9:30 at night, and it was dark by that time. His light was on all day. I've noticed that if his light is on, and the room's dark, he flared, and goes a bit bonkers, lol.
