Long story short... I've had lots of trouble with Sushi from the day I brought him home. He's been through a lot over the past year, but I think he's going to leave us very shortly.
He hasn't been quite right for the past 2 months, but he wasn't showing any obvious symptoms. Because of that, I haven't attempted treating him aside from using a bit of aquarium salt and upping the temp in his tank. Over the past few days... he hasn't been coming up for air. I honestly don't know how he's still alive.
But now... he's all limp, and it looks like his eyes are somewhat sunken in. He's slightly pineconed, not moving and his fins appear almost transparent. He looks so sad.
I have moved him into a container with shallow water. Is there anything else I can do to make him more comfortable? Or at least to make myself feel better?
