Hi! I noticed some odd behavior from one of my rasboras today, where it seems to be chasing another around. It also suddenly had a slightly darker coloration. I didn't know if it was stress related (just added a couple shrimp and did some gravel cleanup), so I dimmed the lights. I do have 4 fry in my tank so I know they're breeding, but I'm not sure if this is related. Are they fighting? My other rasboras seem normal. Any info is appreciated!
