Today I lost another Betta from my Female Sorority! This is the 4th death in like 2 weeks! They all act fine but are dead the next day. 1st it was my new Betta Holly that I only had for a couple of days then died, Next it was Lacey one of my older Bettas, then Spectra several days ago who was my favorite Betta of all, Now today it was a newer Betta Joy.
They all were fine and eating well yesterday but now today, Joy died and most of them seem to have claped fins. Some ate only a pellet or 2 then didn't eat anymore. Some didn't even eat anything at all even when I offered Frozen Brine Shrips and Frozen Blood worms their favorites!
They went back down to the bottom and sat on the gravel with clamped fins. Even while swimming they were clamped fins.
I changed some water and put in conditioners but they still are the same. The water tests are actually better than usual so that is odd.
The only things different lately for the last 3 months is I started using tap water set at around 80 Degrees for water changes. Usually during warm months I use room temp filtered water from the PUR filter water filter container. But it is too cold now to do that because it only reaches 60 degrees in the filtered jugs of water we have water in. (I use it to water my plants) Plus the other different thig is I added 6 Oto Catfish like last week.
