I came home just now to find my CT boy Madara looking very ill..His colors are pale and he's swimming sideways..I'm going to thoroughly clean his 5g now since it WAS time to do a water change..He's currently in a 1g container with half tank water and half fresh water with some aquarium salt, and I put my black sweater over it to keep him relaxed. Please pull for him everyone!
Good news! I woke up this morning and uncovered his tank and he's swimming normally again. There must have been something in the water that was bothering him, but I'm still going to lay off the food just to be safe. Phew!
