My 30g tank was doing great til last weekend when I added 6 new guppies from Petco . Since then I've lost all 14 baby kribensis, 3 guppies, 1 cory cat, 2 Khuli loaches, 3 black neons, and a female platty. The fish look great til they're dying. No ich or fungus - no spots, fuzz, or strings, flashing or darting, and gills look normal. Nobody gasping at the top. Nobody picking on each other. The afflicted fish dies 2-8 hours after it starts looking subdued - top fin clamped, tail low, and hanging out in a corner.
My parameters are great - ammonia at zero (none registering), nitrites 0, nitrates 20-30, pH 6.8 to 7.2, alkalinity 80ppm, total hardness 75ppm. I check several times a week. Temperature is 78-79 degrees. Nothing has changed in the last month except regular weekly 15 percent water changes. I add aquarium salt at water changes at 1 tsp per 5 gallons new water. I'm on private well water so no chlorine. I have a Penguin biowheel and an undergravel filter. The only change was adding those guppies, who must've been sick. (I don't have a quarantine tank. Regrettably. But there's no room for one.)
I just did a 50 percent eater change because it makes me feel like I'm doing something, but it's not gonna help.
I don't know what to treat? Any suggestions? Antibiotics?
