My oldest betta, Shibuya, is a 1 1/2 year old. He's been relatively healthy with little to no health problems since I got him. However in the last few months I've been watching his fins with a careful eye due to mild deteriation along the edges. I dunno if it's tail bitting or mild fin rot, but I figured I'd ask for advice.
What size is your tank? 2.5 gallons
What temperature is your tank? 70 degrees
Does your tank have a filter? no
Does your tank have an air stone or other type of aeration? No
Is your tank heated? no
What tank mates does your betta fish live with? None, he has a neighboring tank with another betta. (not those cheap divider tanks! Two separate tanks)
How often do you perform a water change? Every other day, and at the end of each week.
What percentage of the water do you change when you perform a water change? 50% water change every other day, 100% water change every week.
What type of additives do you add to the water when you perform a water change? Betta Safe(brand) Conditioner
What type of food do you feed your fish? Flakes for bettas, frozen bloodworms.
How often do you feed your fish? I feed him on Tuesdays and Fridays, and a small snack of bloodworms on Sundays.
This was a pic of him I took this morning:
He's missing part of the top of his tail, and down along the ridges. The largest point on the end of his tail is where it normally was.
He did seem relativey sick back in November... I went back to college for the semester, and left him with my younger sister. Of which when I returned for thanksgivign break I found she hadn't cleaned his tank since I left three months ago! D:< I immediately gave him a 100% water change and scrubbed every inch of the tank, silk plants and pebbles to remove any algea, etc. Of which he recovered within a few days.
Because of my sister's lack of fish care, I braved taking him back with me on the windy 5 hour drive back to the college, to ensure his care firsthand. (I left him the first time because I feared he would not survive the trip).
Overall, he seems to be in good health now, the neon green coloring showing, instead of him looking brown. He also seems much better now in 70 degree water than what he was back home. I have a wood fire stove as the source of heat back home, thus resulting in the house being around 60 to 65 degrees. Waaaay too cold for a betta. In attempts to keep him warm I'd put him on the table near the fireplace.
ok.. I'm getting off topic....
He doesn't seem to have any red or black rims to his fins. So I'm figuring it's possibly tail biting? Unsure of what it was, I've been doing 100% water changes, and using a few drops of Melafix, and a few drops of "Betta Revive"(Neomycin sulfate <10%, methlene blue) which have helped from keeping him getting infections. I also placed his tank next to my new betta in attempts to keep him from being as bored. But I still wanted the advice from those with a bit more experience.
