I know this can be a big debate. I hate seeing all the fish at the pet store. So I tried to have a betta sorority. It took a LOT of careful watching. A tank upgrade. And time. I was able to get them as babies and let them get used to each other and made sure they were not stressed. My snail kept laying eggs. I raised the water thinking it wasn’t too high. I was wrong. Some bettas leaped out. (Me now feeling like a murder) I have two very happy fish left. It’s been a couple weeks. I wanted to make sure water was okay and fish weren’t sick and it was just the water level. Sometimes these two nudge the other one out of the way but no chasing and it’s only when they are on “there area” .. so now I’m worried. Do I try to find more the same size and not the same color to recreate the monarchy. Or do I leave these two be??? I’ve heard if there’s no chain over time they can become aggressive towards each other. I found a new home for the snails and will be getting a lid today.
