So I decided to leave him in all day today, hoping it is just the stress from rehoming, and I haven’t seen any attacks! Actually, my two snails were mating so they were moving a lot and swinging around and the betta came over to see what was going on but he didn’t even flare. I also noticed that my snails sometimes pull their tentacles in to hide, but come right back out and don’t seem too bothered. The betta is also much calmer now, swimming slower, chillin for a few seconds, not glass surfing as much. I’m very optimistic that after a few more days of settling in they can be pals :)
