Checked out the fins on each of my female bettas in the sorority tank, added a little melafix and pimafix as a preventative, and did a lady-betta count to ensure that everyone was still alive, active, and healthy. After monitoring their behaviour, I noticed that no one was taking any interest in the new girl, but she was actively trying to get out and explore, so I released her into the tank. She's laid claim to a small area of territory around some terra cotta pots.
I took a whole bunch of really great photos last night of the girls tank and started a journal of future changes to the tank and photos on the Betta Photos/Journals section.
EDIT: I also set my lights to go on with a timer at 6pm until 1am because my landlord is showing the house today to potential new tenants (I move out April 30th), and I don't need him knowing that I have the lights on during "prime" electricity hours. (I don't feel bad about running up his electricity bill because our rent is all-inclusive, and he won't fix -anything- in the house, including our cable tv). I'm writing an essay at the university and likely won't be leaving to go home until 1am at the earliest, so it's not a huge deal to have the lights on at night.
