I am about 4 weeks in to holding some Buces using the egg-crate method. Water is RO/DI remineralized to 5dGH, with a few drops of APT3 and a smidge of Seachem Flourish Advance. Changing water weekly, and misting leaves a little daily with the same water. However, I am seriously considering just setting up a Buce farm tank. While these Buces are doing ok, and so far I have no melt, I am seeing that some species seem to be doing better after the first month, than others. Kedagang seems pretty unfazed by the situation, and is starting to put out new growth, and holding color better than some.
Theia is also putting out new leaves, but is starting to develop palor in the older leaves. I do need to decrease my light a bit, though, as Theia's container was developing more algae.
Not pictured (I forgot to grab a pic, but can update later) is Blackcurrant. It is looking practically sunbleached, with no new growth. King Crocodile is is pushing growth, but both old and new growth is washing out and looking anemic.
I just received some Dark Venus, and Brownie Blue, so I will see how those do over the next few weeks. Once my main tank is planted out, I plan to rescape my shrimp tank, and they may just get to live in a Buce farm tank. I think will be easier for me to keep nutrient levels, and lighting, more consistent.
