So the past few days crush has just not been himself. He slowly started losing energy and his appetite. He is now laying the bottom of his tank, gasping for air. His body looks fine, no discoloration or clamped fins. However hes just barely starting to get stress stripes again. He occasionally comes up for air, but when he does he sinks right back down.
Yesterday he ate his food, but he spit it back out a few times. Now he isnt eating anything.
I put some aquarium salt into his tank. His water perimeters are fine, and his tank is at 75 degrees. Unfortuately i cannot raise the temp, my heater stays at a constant temperature.
