I have a 20 gallon long sorority currently occupied by 4 female bettas, 4 albino cories, and 2 mystery snails. There will be 2 more females coming soon which will lead up to 6 girls. I'm wondering if I can add anymore? And if so, what type of fish?
Shrimp are a no.
The snails need to have a chance to eat. They might get starved from them. The tank is cycled with an Aquaclear 30, heated to 76-77, and aerated with air pump. The pH is 7.6, water is moderate to very hard, GH and KH unknown.. Sand is the substrate. Not planted. Is this really the limit? What do you think? Could I possibly add more girls?
