I previously posted here with the title Black Monday, recounting the loss of three bettas that I kept at the office. Steve is now the only one left, and has been at home for over a week now.
He sits on the bottom, not moving, all day long. When I feed him he'll shoot up to the surface and eat, then go right back to the bottom. When he swims up, he seems tail heavy, and his tail drops and he goes head up until he's perpendicular, then drifts to the bottom. Sometimes he'll suddenly dart around, slamming into the bottom or sides of the tank.
1 gallon jar/tank with conditioned tap water, no heater, temp between 74 and 76. Daily changes of 100%. Light feeding twice a day (just a few crumbs)
I'm wondering if this could be because I switched from the water cooler with RO to tap water (I was told here that RO was bad for them). I had no problems for 1 year, then within 2 months I'd lost most of my guys. The lethargy and sudden darting around seems neurological, so is it possible the tap water has heavy metals, and he has permanent damage?
I'm guessing SBD, but treatment with Epsom salts for a week didn't help. He wouldn't eat the pea, but doesn't seem constipated, not bloated, color is good, scales are normal, breathing is normal.
I'm feeling like this will be the last one for me. My coworkers all miss the fish and ask when I'm bringing Steve back, and if I'll get more. I'd rather have an empty desk than have Death Row again :(
