Abe fAbe is the resident fish. Named after Abe Vigoda, Abe has a prime place in the kitty's house. He receives an enthusiastic greeting from Trixie every morning ("jazz hands!"). One could argue that he's one of the most spoiled betas in town. Even the kitties show him respect.
About a month ago, he had a case of tail rot that we quickly spotted and treated. We used water that we had left out for a day or so, thinking that airing it out would allow the chlorine to dissipate. A friendly worker at Pet World explained that water in our region is infused with chloramine, which can't be aired out. Abe hasn't had any trouble since we switched to reverse-osmosis water.
