I'll grab some zucchini on my way home and try that boiled up. I'll also try setting my tank cooler, though I wouldn't have thought they'd starve themselves to death for a few degreesF for 2 weeks. I'll also see about adding more hiding spots as soon as I get chance to.
I appreciate the info and I'll see if at least the still mostly mobile one perks up. The red one is still moving a little, but just twitching her swim legs now and again.
