I have no idea what may have killed my 4 tiger barbs (tank specs are in my signature, I already took the 4 barbs out of there...).
Here's the scoop. Sunday I did a vacuum the substrate water change (every 3 water changes I make sure to get down to the bottom and in the corners and under the driftwood, etc...) I have about an inch of small river stones/pebbles as my substrate. I've been doing water changes like this for a long time (not deep vacuuming every water change) and the barbs and cories are almost 2 yrs old (the rainbow shark and pleco are almost 6 years old!)
OK so I finish up the water change, go take a shower and get dressed, get my son dressed to go out and put on another pot of coffee for hubby. As we're getting our sneakers on - about an hour after I finished with the water change - my son runs over to the tank and says mommy the fishies are not swimming... 3 of them were belly up totally not moving, and the 4th one was midlevel, also not moving... I scooped them all out, and sort of wiggled them around in the net to see if they moved at all and nada, zip, nothing. So I threw them outside in the bucket.
My husband was across the room on the computer and he said he heard a couple of pops, but didn't think anything of it. He thought maybe they fried on the heater, or got injured by jumping into the filter, but there were no signs of stress, injuries or anything odd about them. What could have happened? Nothing different was done during the water change.
Bizarre mass suicide? Failed escape attempt (they were jumpers, and would often jump up and hit the glass that covers the light, or come very close to getting out at feeding time...)
Thanks in advance for any insight.
FWIW, water parameters last nite were the same as they always were: 0 ammonia, 0 nitrite, 20-40 nitrates, ph 6.5ish and stable temp of 78-80.
