I have a 10 gallon tank that I can’t think of what to use it for and I thought that some smaller cold water species might be interesting to try out. What are some good cold water species that can fit in a 10 gallon tank? (Species only tanks are fine) I’m curious as to what people can come up with. The tank will probably not drop past 60°. It is unlikely to, but might possibly, reach the mid to low 50’s on the coldest nights of the year.
