I've been reading more on the Blue Tang's diet. It's quite the mixed bag, actually. The consensus is that they are plankatores that also eat some algae. I watched a video where a blue and a yellow tang were eating Botriocladia (red grapes) in a clip with gusto. Bottom line, if I don't want to risk my macros, I shouldn't get one. It's possible it wouldn't eat them, but it's possible it would. I really want one, but I better not.
I emailed KP Aquatics about a gramma harem and they said they would have them on Monday, so I should order them then. So I'll likely do that.
On the plant front, the Ulva Intestinalis is still losing ground unfortunately. I found a few more snails on them yesterday. I have no idea how they got there. I'm starting to realize I just can't keep this plant in my tank. I'll keep trying to keep these going, but it's not looking good. It's weird because I kept 'regular ulva' in the early stages of this tank just fine. The difference may be the snails' population, which was no doubt smaller then. With enough plants and plant biomass, I'm sure I could sustain them, but I doubt I can get there. I may be able to blame the Caulerpa, which has a huge biomass, and it slurps up nutrients like a dry sponge. So the Ulva doesn't grow fast enough to outpace predation.
I've been watching the Galaxaura's progress with interest. With all of them in brighter light, their color was lightening. This made me wonder if the info I got was wrong, and they prefer LESS light. On closer inspection with a magnifying glass, I found that the lightened tips were actually new growth. So their coloring may be shifting from a wine color more towards pink. That's fine with me, if they're growing. The last time I kept this plant, I planted it in dimmer lighting and it faded away. So it's nice to see an indication of growth, this time around.
