I currently have a small planted tank (18"x5.5"x7.1") that houses four apple snails. I would like to add either dwarf frog or small group of tiny fish. I do have a light but no heater. I will purchase appropriate filter for tank size.
Any suggestions about whether its ok to move forward and if so, what fish would you recommend aside from Betta?
I've endlers in my nano tanks. They're colorful fish. But I've heater. You can pick up a cheap heater for $6 or so from Walmart.
