Hey guys, this morning I woke up to see Peach chasing around another brownish fish in his side of the tank. I was confused, as I had just woken up and was quite groggy. A closer look revealed that the other fish was Pi! She had somehow jumped out of her cup into Peach's side, and was being chased around the tank by him! I quickly netted her back into her cup and took it out of his tank, then floated the cup in her own tank, which was finally heated to the correct temp. I believe Peach has taken off a tiny piece out of her caudal, but other than that she seems fine. What surprised me the most, though, is that she didn't have a single stress stripe while being chased by Peach, but got them right away after I put her in her cup. Pi is kind of a hyperactive fish, and is the only Betta I have that gets stress stripes at a mere water change of the exact same-temp water..
Here are pictures of her after the incident:
I think that Peach took a little piece off of her caudal:
I removed the other fish that were floating in that tank and floated them in their own tanks as well, as I didn't want this to happen again.
Anything else I should do for little Pi?
