My betta died on Saturday and my mother came home with a new one Sunday, he was perfectly fine yesterday, although he was chasing his reflection, but fins all perfect and there didn't seem to be anything wrong with him. I woke today and his fins are all breaking off, their pale, there's a white mark on one of his side fins and I've just noticed he's lost loads of his scales, on both sides of his back side. I raised the temperature earlier, but now i'm going to put him in a tub with aquarium salt.
What on earth is wrong with him?
The only thing I can think of is, that I added a red tiger lotus bulb and plant on Christmas week and since then I have lost an oto and a betta that I had for years, I assumed he died of bloat as he was quite fat.
