Oh god. I just bought a pack of ping-pong balls tonight when I got off work. I gave the rest of the pack to my 5-year old sibling and saved one for myself.
Rinsed it off thoroughly, and put it in my fish's tank.
He's OBSESSED with it! At first he rushed at it thinking I dropped him a GODLY sized pellet, only to find out it MOVES!
He keeps swimming around it, touching his mouth to it, nipping at it it, jumping at it (trying to bite the writing on the ball)
I took it out when he went behind his filter to hide; and he swam back out and started to LOOK FOR IT. LOL!
I should have done this sooner! What was your betta's reactions to putting a new 'toy' in their tank????
Whoops, scratch that. Now he's starting to flare at it a bit, lol. He jumped at it and it moved a bit TOO much and it spooked him, I think. He flared a bit and now he's circling back around it.
