This morning my dad woke up, looked over at his 10 gallon fish tank and noticed all 6 of his cardinal tetras were dead! OVERNIGHT! The other fish in the tank are fine, and simming around, but we're worried that somethings terribly wrong. Here's the low-down on things that have recently happened to the tank (since he's had the tetras for about a year now and they've been happy).
a few days ago he replaced the carbon in his filter. He used some stuff that I had bought for an emergency goldfish tank about a year and a half ago. It was carbon with amonia reducers in it.
Last week I got tired of looking at a moldy tank with thick algae so I scrubed down the sides of the tank with a scrubber that has only been used for said purpose; changed the filter; rinced the canopy and filter holder out with plain water; took a small amount of gunge from the bottom with a syphon; replaced the 2L's of water that I took out with room-temperature water without chlorine; and bought him an algae eater.
They've been fine till this morning. I've suggested him buying a water testing kit and going from there, and I pulled the filter out in case it had something to do with this.
Anyone know fish?? Can anyone give some adivce?
Thanks!
Jess
