Hi, need some help on my betta please. It's been shedding its fins and losing color lately and has been generally depressed. Pimafix and melafix has not helped.

It's usually in a 10L tank (but now in a smaller hospital tank), 50% PWC twice a week with Prime. Parameters are all either low or none. Before/after photos below. Would greatly appreciate a diagnosis/medication suggestion!
