We have a new female Betta (named Roberta, after her predecessor) after a 6 month gap.
She seems to be adjusting pretty well; didn't eat much the first few days but eating well now.
I have a heater for her tank, which I didn't have before. It's a small flat 15W plug-in heater that sits on the bottom of her 1-gal tank, under the glass rocks. She likes to hang out as close as possible to the heater and has actually sort of burrowed herself a little cave to get closer to the heater (cave is under the lip of the larger piece of coral that her plants are stuck in.) I worry whenever I see her hanging out near the bottom, but then she comes up and swims around well -- so I think it's just preference (warmth and maybe hiding?) Wondering what you think and whether other fish do this?
Thermometer shows water temp between 70 and 75 degrees F
Second question is about females making bubbles. I know from threads on here that males do that when they're happy but couldn't find anything about females doing it. She has about 8-10 bubbles on the top of her tank. Not all in a cluster. But they're pretty viscous and stay for a while.
