Hey guys,
I've just started a new tank about 4 weeks ago, and I've run into a bit of a mystery...
It's a 29G fresh water tank, fitted with T5 high lighting, Flourite Black, water Wysteria, java moss, and dwarf baby tears. Temperature is at 75F/24C. I've got a hang on the back Aqueon filter with carbon media that's been running for 3 weeks, and the water has treated with dechlorinater at the recommended dosage. I introduced some neon tetras to the tank recently, and things got weird.
They're perfectly fine for the most part. Active, colorful, and hungry. But every once in a while, I'd observe one stranded fish stay near the surface, gasp for air for a couple of minutes, then finally freak out and die. The odd thing is, the school is not gasping for air on a regular basis. Most of them stay together toward the bottom half of the tank. It's been a few days, and I've lost 4 in this fashion.
What could be the cause of this? I mean, if the water is that toxic, shouldn't they all have died when I introduced them to the tank? It's been days, why be fine and then suddenly gasp for air and die?
Please halp!
