(I know, my algae is gross )
So a few days ago I noticed that my betta's head was reddish/yellow, which it had previously never been. It doesn't look powdery or anything, and not quite like other pictures of velvet I've found online, so I was wondering if this was velvet or something else or maybe not even a disease. She is still very lively, very excited to flutter up and say hi when I walk by, interested in eating and nipping at my fingers, but the discoloration (?) has spread a bit, possibly onto her back?
size: 5 gal (Fluval spec V)
occupants: betta (female), nerite snail. Betta is young, I got her from the store in early March.
pH: somewhere between 7.8 and 8.0 (and hard judging by the deposits on the sink aerator)
nitrate: between 0 and 5
water change schedule: weekly, about 40%. Includes siphoning up muck that settles into the sand. Monthly swishes of sponge filter medium in old water to clean out gunk.
lights: usually a Finnex programmable LED light that has about 8 hours of daylight with reddish sunrise/sunset and twilight phase, lights are fully off for ~8 hours. Currently the lights are off because I've been battling a green hair algae problem (as visible in the picture), but not in full blackout. I noticed the color change in the betta before turning the lights off.
(All tests conducted with liquid API test kit, including shaking, rattling, and rolling the nitrate test bottles. I have a philodendron hanging its roots into the water so 0 nitrate is not an impossibility given the size of the tank and its occupants. Tank has been cycled for years.)
Thanks in advance!
