Hello,
I'm gonna just get to the point here. Over the past month I would say I have slowly lost several fish. My tank is stocked with guppies, neon tetras, cories, 2 bolivian rams, and a highfin pleco. I have a 29g with a topfin30 and topfin 60 filter, standard heater keeps the temp 80-82, gravel substrate. I have lost probably now about half of my I would say 20 guppies, and all 4 cories. All deaths have come without sign of disease, or sign of anything to be honest. Basically I experience 1 death about every 2-3 days. At first it was just guppies, I've kept guppies for years and a couple died I didn't think much of it, but it kept happening, juveniles began to die, then the cories died off as well. All 10 tetra, both rams, and the pleco have not experienced deaths. Only the guppies and cories.
Unfortunately I think I may know the cause and now need advice. After cleaning one day I was trying to move the thermometer and holy crap I don't know my own strength. I squeezed the suction cup so hard I ended up shattering the glass somehow . The little beady looking things and some glass fell down into the substrate. I immediately cleaned it out and watched for any suspect behavior but didnt notice anything strange. Now after all the deaths and noticing that the red fluid (is it still mercury?) in the thermometer in my SW tank I realized that it along with the glass in beads fell into the tank. I believe this is what is causing my deaths, but why does it seem to only be the cories and guppies? I have a picture of what has happened to the gravel where the glass and beads fell, not sure what to make of it. Please someone, anyone, have any advice on this?
