Pardon my long response time everyone, the past week has been a very hectic one! Thanks to everybody for all of the input and suggestions, I have a lot to think about for aimara proofing her new tank!
Good news! She has calmed down and stabilized quite a lot over the past week or so once she beat her bout of ich. She's been eating Massivore stuffed smelt and tilapia fillet, but seems quite timid when it comes to feeding. She is only interested in food about every other day, and it generally takes her half an hour or so to work up the gumption to eat it.
I managed to get some good friends together to help move/set up the 240, so it is finally in place, and will be ready for her in short order. The current configuration is bare bottom, black back and bottom, two large pieces of Malaysian driftwood situated in a way to produce a large hide, and about a dozen 10"-12" Indian almond leaves scattered on the bottom. The tank (8') is lit by a single 48" T8 bulb, producing a nice dim feel to the whole setup. I am torn between keeping the tank bare bottom, or going with a light "dusting" of a coarse grain sand.
Filtration has yet to be figured completely out, but I have a 30 gallon sump that came with the tank, and I was thinking about combining it with an FX6 for maximum water movement (which is currently being supplied by two oversize powerheads). My main concern with the sump is in keeping the water level lowered by several inches, yet being able to have water getting into the overflow box. <---- Thoughts?!
I am leaning towards adding a school of 15 giant danios to keep a bit of action in the upper reaches of the tank, as well as keeping her feeling secure. She's currently alone in the 75, since I'm extremely hesitant about adding any fish to her currently small tank and stressing her out or bringing about another round of ich. She had 5 danios in the 75 from day one, but she ate the last one the night before last. Hopefully she'll pay the dithers a little less attention when in the 240!
