I recently sorta "inherited" a tank from my sister who decided she no longer wanted to keep it.
Its fully cycled, has some live plants, and has been up and running for some months now. (not sure exactly how long)
When she set it up there were some water issues, she is on well water and found out its copper content was way high. So it was put on RO water under her care and has done fine (other then algae overgrowth) since then.
She brought it to me about a week or so ago, it had 3 female bettas, 1 platy, 1 whitecloud, and 3 otos in it. I have given away the platy and the whitecloud. I also added another female betta (after jarring the whole lot of um for a few days)
I have kept fish before, so am not a novice at this. I also have a 5gal and a 2gal both with just a single male betta each. The 2gal is unfiltered, the 5gal is newly set up and cycling right now (with a piece of sponge from the 10gal, and a deco piece also from 10gal with some algae along with a few pieces of hornwort)
My questions have to do with the sorority thing though. I've never had female bettas before, much less in a sorority so I'm still learning about this aspect.
The newest one (also smallest) seems to be the bottom of the pecking order. While this is no surprise, I am a bit concerned because the others keep preventing her from eating. I just put them all in the 10gal night before last, so I know she won't starve anytime real soon, just wondering if anyone has experience with this?
Also she seems to be resting mostly on the bottom today, she is going up to breathe though so I have not pulled her out.
The tank got fairly cool (about 72) overnight as we had a cold front come through with storms and the house dropped farther then I expected. Could this temp drop be the cause of her bottom resting?
Obviously the tank is not heated, since my house normally sits at about 76 in the spring and summer, and my sis never uses one, I had not even seriously considered putting in a heater. I have a couple, from the years of fish keeping before, but have never used one either. I keep seeing people say the bettas need them though? Any thoughts on heat vs no heat? Also is the sorority more important to keep heated? As I said I'm still learning here, crash course, about keeping a sorority!
Thanks in advance!
