About 8 days ago, I recently got a veiltail betta. He started out with a 1.5 gallon tank. Then moved the betta to a 10 gallon tank 2 days later, along with a whisper filter and some decorations. (for artificial plants, it's silk.) Adjusted the height of the filter, as the "water fall effect" was causing too much of a strong current. Everything is fine now. As my previous betta keeping was pretty bad, (I was really young, it was kept in a bowl ) I observed his behaviors and any signs of possible sickness. (did some heavy research before I got the betta, so I don't make the same mistakes.) Everything seemed fine. He was eating normally, came up to me when I go towards the tank, fins and scales looked healthy. Nothing unusual.
Then about a day later, I noticed him making a bit of a terrible bubble nest. Based on size, my veiltail looks young. He's about 1.5 or 2 inches. What I mean "terrible" is that the bubbles he make are a bit far apart. I even saw him making the nest and he wouldn't put them close together. There are no strong currents to move the bubbles, and he started making them away from the filter, at the side of the tank's left corner facing me. By the end of the day, I noticed his aggressive behavior. Whenever I hover my hand for a second to drop a pellet, he jumps and bites my finger. Whenever I'm near the tank, he swims side to side and even flares when I look at him.
Maybe he's just being territorial? I guess another question is: do male bettas get aggressive during and after making a bubble nest?
I'm just trying to make sure. As I mentioned here, he wasn't doing any of this for a couple of days after I got him.
