I joined this forum because I need advice. I inherited a 10-gallon tank with 1 giant danio from my recently deceased boyfriend. Actually, it is his cat's tank which I also inherited. Yes, he loved his cat so much he got her a pet. He told me once that he wanted to give her something to watch while he was at work so got her a tank with a giant danio. when it died after 7 years she sat on the tank hood (she's a tiny thing) and cried and cried until he got her another one. Actually, he got her 2 but the surviving fish is apparently something of a bully in that it incessantly chased the other one until it finally committed suicide by jumping out of the tiny space left by the opening for the filter and the heater.
I understand that a 10-gallon tank is really quite small, but I don't really have room for a larger one. I was wondering if there were any other hardy fish I could keep in such a small tank, specifically I was thinking of a bottom feeder. While I do have a heater for the tank, I don't have air conditioning. I live in the San Francisco area and get their water supply which is a bit on the hard side. I do have a chemical additive that is supposed to buffer to a pH of 7.0.
Also, right now there are only plastic plants in the tank. Does anyone have any advice on live plants that would tolerate hardish water that can get a little on the warm side. (remember no air conditioning)
If it gets really hot should I put ice in the tank? If so, should I be freezing special fish tank ice?
I am new to tank ownership but I consider myself a responsible pet owner and want to do what is right by this fish. I don't have a name for it and I don't know what the cat calls the fish. The cat's name, by the way, is Little Misty.
Thanks for all your help in advance.
