AQueerium

She wasn't lethargic, she eagerly ate food yesterday still struggling with swimming and spotting the food but seemingly better than the days before and I had some hope she would have recovered... but today was her last one. This morning she was heavily breathing on the bottom of the tank and I had to go to University hoping I would see her one last time coming back.

I found her lying in the front part of the tank where I usually feed her...

She was lethargic and near death when I bought her and it was a stark contrast to her amazing excitability she had once I found the right food for her.

Puppy sadly hasn't been doing too well recently. She struggles swimming (her fins are still there but she seems to have issues with her spine), has been very tired. Her lower fin has had finrot recently but it has started to recover. She was majorly underfed when I got her. That was two years ago. I feel like this might just be her getting old.

Nothing major just wanted a new setup to distract myself with. First time using co2. No animals yet decided for, but maybe some out there shrimp. I like keeping dwarf shrimp that aren't mainstream but easy to keep.

I also created a 3d printed Filter enclosure allowing it to suck water through the crushed lava stone. There is definitely a strong current going through the ground which was a big success. Makes it likely that the effective bio-filtering is far stronger per volume of water than it is normally for inside the tank filters.
