Got this expensive piece (I believe is a trachy..) about 3 weeks ago, and it's/was beautiful and thriving. Did first water change last week and since then have seen two bands of white tissue that have now joined together and seem to be spreading. All parameters stable 79.1 degrees, 8.3, calcium 500, KH 10.5, 0 all bad things. Haven't noticed my clowns, chalk bass, or inverts bothering it at all. Any chance to save this beauty? Doesn't look like brown jelly to me
