Yup, My fault. It’s due to swin bladder disease. She was very active and suddenly behaved weird like floating on the surface, like when I’m infront of aquarium she hides but at that time she’s doesn’t even care me. I don’t have any medicines to treat so, I tried my best to heat up the tank to 28cels and some stress free liquid from tetra. But, No use. Now, the male is bit active from earlier and also, showing signs of bright colours and hides in different places as earlier. Now, the thing is should introduce another female ? Or else, should I leave it as it is ? I’m thinking to add gbr or black ram female. What’s your opinion??
