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
Hey.
Need a lot more info to help you figure this out! Were they moving around a lot in the tank where you bought them? They tend to be more active when they have fry. How long have you had them?
Did both the dry and parents have signs of fungal infection? Aka fuzzy, cotton-looking stuff on the fish/in the tank? If you are sure it was fungus, put in 5 g more/10 liter of however much aquarium salt you usually put in. If they're breathing is quick, raise the output of your filter to give them more oxygen into the water.
What temperature is your water?
Have you tested your water? Do they have places to hide, and surface cover such as floating plants? How is their breathing? Quick shallow breaths and them not coming up for air could be a sign that they're sick and/or stressed.
Try to stay calm and not disturb them too much. If your plants can handle it, turn the lights off or lessen amount of time they are on.
