Dealing with something I'm afraid may be contagious. I've lost 9 danios slowly starting about a month ago. Lost one white cloud minnow two weeks ago. Everything has been fine for the past week. Have two more white cloud minnows now showing symptoms. I thought it was the large aggressive female danio harrassing and killing the other fish, but she's been moved out and the white clouds have just started showing signs.
Tank size: 20 gallon
pH: 8.2
ammonia: 0
nitrite: 0
nitrate: 20ppm
kH: 300ppm
gH: 300ppm
tank temp: 78F
Fish Symptoms (include full description including lesion, color, location, fish behavior):
Fish suddenly getting very emaciated within a day or two - sunken in sides and stomach. Seems to show a slight arch in the middle of the back, but it may be due to loss of weight. Fins slightly clamping the next day. Fish gets a bit pale and stops being active the following day. Death occuring a day or so after that. They ARE eating during this time. There are no signs of leasions, sores, worms. They look like a perfectly healthy fish except for the sunken abdominal area.
Volume and Frequency of water changes:
1/4 once a week. With the first sick fish (three of them at once) I did a 3/4 water change fearing it was ammonia or nitrite and had no test strips in the house to confirm it.
Chemical Additives or Media in your tank:
Use Prime to condition. Have one carbon insert in the filter and two foam inserts.
Tank inhabitants:
At the moment, 5 white cloud minnows and 7 black kuhli loaches.
Recent additions to your tank (living or decoration):
8 danios five months ago, all but one dead. 6 white cloud minnows two weeks ago, one dead immediately.
Exposure to chemicals:
None, tank is in bedroom.
Please help! I want to add more white clouds but am afraid to until I know what's going on! I do feed a mix of foods and know even the sick fish have been eating. They get a mix of Wardley flake and pellet, frozen bloodworms and brineshrimp.
Thank you!
