We are a mother & daughter in New England. We have 1 10 gallon tropical freshwater tank that was just set up in early January. The first fish (3 harequin rasbora) were introduced 3 weeks ago. Last weekend we introduced 2 otocats and 1 male fancy guppy. Sadly, despite a very gentle introduction, we lost one of the otocats the first night.
The surviving one is doing well.
We have hard water with a pH of 7.4-7.6 and are looking for advice on hardy fish that thrive at this pH.
