Are their fins up? oto's clamp their fins if they are even kinda almost alittle stressed.
No, they're happy-looking and active. It's ironic, just a day before #9 disappeared, I was taking a break from work to watch the otos swim around during their most active time of day, at sundown. And I thought, "It's so nice to have this tank finally settled down, easy to care for, and fun to watch." It'd been a long road from being a newbie to having a healthy 55 gallon. Or at least I
thought it was healthy!!!! Of course, the next day, Mr. 9 disappears and I'm all stressed out over the tank again :headshake2:
