I had a 5G tank with 2 males, 2 females, when I had my first batch of fry.
I highly recommend live plants — I have a hunch that the fish actually do notice the difference… for one thing they “smell” different. And more oxygen in the daytime. Lots of benefits with real plants! One of them might be, depriving algae of nutrients so the snails have less to feed on, thus reducing their population. Experiment with it, just my humble suggestion.
