I'm new to fish keeping and recently got a ten gallon tank with four female bettas. I only had them for three days now and they seem to be timid and don't really interact with each other so far (this will probably change). I have a driftwood and 2 caves for them to hide in as well as 5 plants. Am I able to add more tank mates and if so, what kind? If not, is it overstocked?
Any other tips for a newbie betta keeper would be appreciated.
