Is this Spencer? Is that the RBTA you got from me at the meeting? I have no idea why mine has stayed that color for the past 4-5 years. It has split many times and I have 4-5 of them that are upwards of 6-9" wide and still stay pink like that. Looks a little more white than when I removed it from my tank, but I am sure that is a bit stressful for them.
Hope it colors back up and maybe turns the deep red it should be! Nice to meet you last weekend.
Nice job on the tank cleanup!! Looks great and good luck with it, very nice start!
