Okay, so I’m a little bit worried here. Two days I transferred my 7 harlequin rasboras from my 20 gallon to my 45. Everything went smoothly, but then I noticed that one of the 7 wasn’t schooling and was hiding in the corner of the tank behind some driftwood. I was concerned, but then later it joined the school. However, yesterday when I got home, I found a rasbora on my floor dead. It had somehow jumped out of the tiny gap between my heater and my aquarium lid. I was upset, but didn’t think that would happen again. But today, I’ve spotted one of the remaining six rasboras hiding in the corner of the tank not schooling with the rest of them, and staying behind that very same piece of driftwood. Now, I just added a bunch of new plants so it might just be stressed out because of my hand being in the tank a lot, but it concerns me that it’s in the exact same spot that the previous rasbora was. So should I be worried, or am I just blowing things out of proportion?
