I'm sorry, I can't get a good shot, they are all blurry :/
So as I said above, I noticed this one tetra last night hiding under a rock in the gravel. I moved the rock, and he (or she) swam off, and went back to the school of tetras. The this morning, I come out, and he's on the other side of the tank, under a rock, obviously dead. So I pulled him out, and I the only thing I can see is the area under his gills, and back a bit is brown. He's a bit faded, but I assume that that is caused by the fact that he's no longer here.
I'm a bit sad, this is my first loss, and I'm glad I have a large school of them, otherwise my three year old would be asking questions :/
But in saying that, I have noticed this morning that my betta has been picked on, his tail has been mauled, and he's taken to hiding under a log, and flaring and chasing off anything that comes too close. They've been getting on fine for several weeks now, and now this?
Any ideas and advice is gratefully received...
