Is that from the batch of pink Birdsnest I sent down south?
No. Just either pissed, acclimation or too much current. It looks like regular birds nest without PE thats all.
This came from my tank high up, PAR probably 300-400 or so. Moderate to high flow. But birdsnest is very forgiving to different situations. It doesn’t need those parameters to thrive. Just needs a few weeks or so to settle in and acclimate to your tank.
