So it begin with a purchase of a pair channa gachua/limbata 8 months ago, I seriously don't know which is it. And they came with 100+ fry however due to fungal infection I guess and all died. Its my first time keeping channa so I feel kinda bad. But now the both parents are not really swimming and decided to stay on the ground. I have tried to remove all the decoration and isolate both of them individually but they still stay the same. I hope some with experience can help me with this issue. THANK YOUUUUUU
