I don't think they'll die in the first few hours. I'm thinking more like the first 3-4 days. And why on earth would you be keeping them in a tank with a predatory cat that could easily snack on them? What is the matter with you?
hrmm wes from rare fish had the target fish in the same tanks as dats and i assume that it was freshwater. and they were doin prefectly fine. i plan on picking up some this week. so u will be hearing some questions
