After 30 seconds into feeding my fish last night one of my Acei went head first into the sand substrate and plowed himself in a good 1.5 inches. After he backed out he floated on his back on the bottom and appeared to be shock. I needed to go to sleep and didn’t have time to check on him this morning, what’s up with that? Also, my Acei were always a nice solid purple in color, as of last night (all of a sudden) they have pronounce veridical dark stripes on them. They look great, but what happened? They have already bred once around a month ago; they are around five moths old. Thanks..
