Hi Guys,

Just a warning based on my own experience, a flying cockroach flew into my bedroom yesterday and hid behind a cabinet where I placed 2 nano tanks, one only had 01 X yamato, the other had 01 X yamato, 02 X orange, 01 X bee and 01 X tiger.

As it was close to bedtime (I don't believe any of you can go to sleep knowing that there is a flying cockroach lurking around in your bedroom), and I couldn't lure the cockroach out to the open enough to get a clear hit at it, I took up a can of Shieldtox Rapid Kill and sprayed at the cockroach through the gap between the wall and my cabinet to kill it.

This morning when I woke up (after about 7 hrs,) I found both the yamatos kept separately in different tanks dead while the rest of the shrimps were perfectly fine. I believe some of the toxins (from the web, active ingredients stated are imiprothrin and cypermethrin) from the Shieldtox must have settled into the nano tank and these must have killed the yamatos.

Considering that my tanks are 1 ft nano tanks and that the rest of the species of shrimps did not die, I believe the quantity of toxin which entered should be quite minute. Can I therefore deduce that yamatos are very sensitive to the toxins contained in Shieldtox? So guys, think twice before spraying such pesticide around a few metres vicinity away from your tank containing yamatos!
