Aquarium Advice Apprentice
I have purchased 6 kuhli loach and so far 5 of them have died in a week. They would sit at the bottom of the tank, spin in circles and shake really bad, curl up and die. I do not know what is causing this and I do not know how to prevent it. One is fine and he has been eating brine shrimp and swimming around for the past week. My water parameters are 0-0-35. My nitrates are low at 35 ppm and their are no fish in the tank that would be picking on them so what could be it? Their is sufficient oxygen in the tank with 2 air stones, i have a large filter, and I do 30-35% water changes weekly. I would like to purchase more of them, but I do not want this to happen again.
