Sad news to report. Monstro, our biggest, baddest fish died last night.
It was quite a surprise and he seemed to get ill very quickly indeed. When we left for the office all the fish had looked fine and appeared to be in good spirits. However, when we returned poor Monstro was swimming around frantically at the surface and often flipping over so he was upside down. All his fins looked terribly frayed and disintegrated.
We pulled him out and put him in a separate bowl with some Stress Coat and a mix of old and new conditioned water. He seemed to calm down a little but didn’t last much longer after that. Bill checked back on him just before we went to bed and ended up taking him outside for burial.
The rest of the fish got a hefty water change because the only problem we can think of it that we have problem water. A ph test showed that our alkaline tap water turns highly (in a fishy scale of things) acidic in the tank and testing for ammonia revealed high content there.
Hope our three remaining fish are going to be okay. We have Pootle, New Guy (Bill refused to name him after our first fish died) and Cthulu (aka Plecky)) left.
