Im going to put a lot of planning and effort into the sorority that I'm going to start, and getting the right fish will be a big part of it. I'm going to have about 10 for now, and upgrade to a bigger tank later, but I have a question about adding the new bettas.
Im definitely not going to buy all of them at once, some will be pet store rescues, some I'll buy online. It might be several weeks even months before I stop getting fish, depending on shipping times, availability, and just me having the time to go buy new fish. So my question to you is how do you add new bettas to a sorority gradually. I know that it's better to add them all at once, but I don't know if that will be possible. I think it would be cruel to keep them in smaller containers until I'm ready to put them all in, but if I add them one or two at a time, will they be bullied? And are there any alternatives?
