today I was cleaning my tank, my biggest barb was floating upside down. I had a look in the tank and she was't floating at that time. then I took the top off and got myself a desk lamp for above the aquarium so I can see what I'm doing when cleaning the tank. then I took the top off.
so it must have happened in these few seconds...
I first tought she must have died becouse she was probably old. but then I saw their was a chunk out of her back wich looked like it must have been a bite(when I took it out of the water their was blood coming out of the wound).
it could'nt have been a stone or anything in the aquarium becouse they lay in the sand.
the only fish I have are some cory's and 8 other barbs, so I don't know what could have happened.
does anyone have an idea???
I don't think it was an health problem becouse she was the most beautiful barb of the whole clan... you can see if a pentazona is healthy if it's nicely colored and striped.
I had a little funeral in the bathroom and flushed the poor thing.
rest in peace, you where a good fish.
