Hey just a quick question about my Harlequins: This is the first time they started doing this. They just group and hover in this same spot for hours. Water parameters are optimal (Ammonia , Nitrite 0, Some Nitrate, temp is 80F and ph is 7.4 - same as tap, did not want to chemically alter water) Tank is planted 10gal, 6 rasboras and one male betta. Didnt want to add more rasboras in fear of overcrowding.
Is this behavior a normal thing or should I be worried? I attached an image
