i got him about 2 days ago i saw him for the first time today because hes been hiding in the sand since he was introduced, well i noticed he had red eithier on the inside or outside of his gills i couldnt determine, all my water params is perfect and all my other fish have been perfectly fine considering this is the newest addition in a little bit, anyone else have experience with these fishes? btw he was perfect when i took him home from the store im kinda concluding maybe it got irritated because of him diving into the sand? maybe he hit a rock or something on the way down im not to sure
