I don't know why, one of the shortnose was dead when I got up this morning. Didn't have anything visibly wrong. He was floating on his side at the surface, with a slight curve to his body (he was curved to the side, not up or down).
I don't think he ran into the glass and broke his back, it didn't look like that. Anyone have any idea what could have happened? He was one of the largest and best looking too.
Should I go ahead and transfer 1 or 2 to my larger tank?
I'm doing a 50% water change as I type this.
