I moved the girls into their community tanks the other week after a cat dropped the makeshift lid of my 2.5 gallon divided into their tank while I was away. D= Yikes. Really the lid was just that plastic mesh just like the divider but I don't know how long poor Deema had to gill breathe. She took a huge gulp of air when I pulled the mesh out. So that was terrible, almost really terrible. My bad. The 2.5 gallons have glass lids too but I have those little Hydor pad heaters with no temperature adjustment (on second thought, not a great idea) and with the glass lids on the 2.5 gallons get too hot. They stay 80-82 with only the mesh on top. I don't see how you could use them with a 2.5 gallon for anything but a betta. Such a small, hot body of water.
Nonny is growing out those fins, getting a dark edge on his caudal. He's still in a 2.5 gallon I've been doing 100 percent water changes on, but his fins are getting long and I want to stop manhandling him so much, so I'll see if he'll get along in a community tank soon.
Deema is getting along with a couple random fish in a 10 gallon pretty well, as far as I can tell. That patchy marbling is filling out on her sides and her fins have a bit of a shine.
I think Oona doesn't really like living in the tank I introduced her to, though. I think she's the territorial sort, as often as she was barred up before, and doesn't like that even the random dwarf platy in the tank is still bigger than her. There's only a total of three fish there and it didn't look like the other two were bugging her or anything. Her fins look intact, she's active and rabidly hungry. I don't think she's sick, she just doesn't like it. I'm going to cycle the 2.5 gallon she was in before and move her back to her own territory when I've got stable water conditions in there.
Oona is not pleased. I've got some adjustments to make.
