That’s false! I have a few with white growth tips including a slimer… bill murray, wwc after party and my slimer just to show a couple.Not to shame anyone, but acros don’t have bright white tip growth. I’ve just come across this thread and I think lighting might be the issue on this piece.
Your slimer is STN’ing, do you have any other acros in the tank?
It’s been a week so this issue may have been solved already but I would like to offer advice if it hasn’t been yet
