I've just decided to try my luck with bettas again after not having an aquarium for several years. Today I came home to find a weird mark on my betta's head and want to be sure I diagnose the issue properly so that I can get Ruthie back to good health.
Tank Facts
>6 gallon Marineland pillar
>Attempted to cycle a tank for the first time with this one, ammonia levels were at zero when fish introduced
>All decorations, substrate, etc cleaned with water that had been treated with Tetra Betta Safe before introduction to tank
>Tank includes the Betta Log, Betta Leaf Bed, a mock driftwood piece, two marimo moss balls, indian almond leaf (changed if it starts to sink, have a pack of them), and only silk plants
Water/Fish Treatments
>Water treated with Tetra Betta Safe before being added to the tank.
>My betta had a small piece of his fin missing when we brought him home, so I treated him with Hikari Betta Revive for the first two days
>API Stress Coat Water Conditioner added to water
>20% of water changed weekly
>I've been testing for ammonia every day since it was my first time trying to cycle a tank. I noticed that the ammonia level was at .5 so I changed 20% of the water again mid-week. The next day it was still not at 0, so I did use some ammonia remover in the water.
>Tank temperature kept at 80.2 degrees and checked with in-tank thermometer regularly.
>Fishie eating Betta Pellets daily and freeze-dried blood worms every other day, only what he can eat within 2 minutes.
My Betta (Ruthie, yes I know it's a male fish) came from a Petco a few weeks ago with a small piece of his dumbo ear fin missing on his left side. Since adding him to his tank (very slow introduction over 24 hours, slowly adding water from new tank to his container, letting the container float to adjust to temperature in tank, etc), he has been very active, seemingly happy, exploring his new environment, resting on his betta leaf, and generally loving life.
Today i noticed the spot on the left side of his head as pictured below. It looks like it could be a missing scale, but I wanted to post it here to be sure it's not ammonia burn or something else unpleasant. I've been working really hard to keep the ammonia out of this tank, but have been having trouble cleaning such a small tank with the manual siphons, so the water is still a bit cloudy even after changing 20% of the water two days ago (am ordering a different style pump). Any idea what the red spot on his head his?
