Hi, I've never posted here before. I have a planted freshwater 20g with 4 mollies in it, some fry & a juvenile BN pleco it's been running for about 1 year. I have not had illness in it since August- there was 1 fish with a fungal infection. A few days ago my male sailfin molly started exhibiting odd behavior. Tail standing, head up, and spinning around. I cant find any other symptoms. I've kept mollies for upwards of 7 years & have never seen this before. No others in tank seem effected. I added new plants a few months ago but I always QT them first.
Parameters: Ammonia: 0ppm Nitrate: under 20ppm Nitrite: 0ppm Chlorine: 0 GH: very hard 150-300ppm Alkalinity (KH) 60ppm PH: 7.6 temp is set for 78°
Tonight I came home & he was curled up at the top of the tank inside a floating water sprite with 2 week old molly fry. Im baffled. I posted this on Fishlore a few days ago but no replies. Hoping someone can help! Im unsure of how to upload a photo.
