Puff was in the 10 gallon tank with 3 cory's. Now he is, ah was , the goldie who had lost his tail quite sometime ago; started to grow back some; other goldie picking on him; transferred him to 10 gallon.
He had red streaks awhile ago in 2 of his fins, but this eventually cleared up. Then, he looked as if he had cloudy eyes. I treated for a week with Melafix. The eyes seemed to have been cleared.
Anyway, the last couple of days he had looked as if his mid-section had "sunk" in a bit. Was still eating fine, swimming as of Friday night. I left early Saturday in a hurry so didn't take a look at him. Came home last night, he was a mess. Most of his tail was gone, the mid-section was REALLY sunken in. He wasn't moving, eating, nothing. He was no longer a pretty calico color and was breathing very heavy. He died today.
The tank water wasn't clear but I thought this was due to the fact I hadn't been cleaning the glass, wanted to get a build up of algae to get a new algae eater. It was due for the weekly water change, but since he had been sick I wanted to clean everything. I also did approximately a 50% water change. SHOCK, the color of the water was ah, I can only explain it as saying it looked dirty, almost dirty bucket of water used to clean a floor.
When I took the filter out to give it a swish, I realized I forgot to put the carbon filter back in. Now I know the carbon itself is no big deal; however, this filter has the carbon and blue "stuff" in one. So you see, the only filter was the bio filter.
So, with only the bio filter would this have caused my water to be so dirty? And, could this resulted in my poor fishies condition that led to his death.
Sorry, so long but wanted to try and explain what led up to his death.
