I've had an ongoing problem with harlequin rasboras dying one at a time, and I think it may be from stray voltage. Tell me what you think:
---------------
Main tank: Marina Slim HOB (motor in the tank), Via Aqua heater, battery-operated temperature probe, dual All-Glass fixture (on glass lid, not open tank).
QT tank: Nano HOB, Cascade heater, no light.
Both tanks plugged into the only available outlet, which is not grounded. I'm looking at fixing that but in the meantime ... Will adding a GFIC plug/powerstrip do any good on an ungrounded outlet? Will changing to a canister filter and inline heater (which I'd like to do for a variety of reasons) end the problem??
- The only symptom shared by all fish is an abrupt change in behavior. The fish begins twitching its fins, swims repeatedly around and around the same area of the tank, ignores other fish, stops feeding (due to lack of interest or inability?), and eventually loses buoyancy control.
- The fish may die within hours, or go slowly downhill until I euthanize it.
- I'm not seeing HITH, body wounds, bloody streaks, popeye, dropsy, fin damage, or parasites.
- What I thought might be a fungal/bacterial infection turned out to be (I believe) a heavy slime coat and graying out loss of color.
- Treatments with Maracyn Plus (main tank) and Seachem ParaGuard (QT tank) have had no noticeable effect. Seemingly healthy fish fell ill and died during the treatments.
- MT snails and amano shrimp are perfectly healthy and happy.
- Water params are fine, testing repeatedly with API liquid kit.
- All deaths have occurred in the hours/days right after water changes — during which I usually unplug/replug HOBs and heaters.
