Hi, I was hoping maybe someone has experience with strange bumps/injuries on bettas. My betta Charlie has had this bump on his nose. Picture below.
What size is your tank? 2.5 gal
What temperature is your tank? 74-78 degrees (it fluctuates since our house has horrible heating issues)
Does your tank have a filter? yes
Does your tank have an air stone or other type of aeration? no
Is your tank heated? no, unless a nearby lamp counts
What tank mates does your betta fish live with? none
What type of food do you feed your betta fish? Hikari bio-gold pellets
How often do you feed your betta fish? 2 pellets, 3 times a day; used to feed him frozen brine shrimp once a week (no pellets that day), but since the bump appearance I ceased in case of ich contaminants.
How often do you perform a water change? approx 3 times a week, no schedule yet, it depends on algae and ammonia/nitrate
What percentage of the water do you change when you perform a water change? anywhere from 10 to 35%, over the course of a week no more than 40% or so i think
What type of additives do you add to the water when you perform a water change? Since I use bottled water (my well water is too high in minerals, pH of 8 or higher), I do not use a dechlorinator (i checked with the bottling plant, it is indeed chlorine free).
Have you tested your water? If so, what are the following parameters?
Nitrate: roughly 1ppm (maybe more or less, my kit's first color block is 0, the second is 5ppm...not much of a middle ground there)
(to address the ammonia issue - yes i'm aware it should be 0. the tank has cycled, but there is a remaining .25ppm. it's been there for about a week. i keep detailed charts and measure it daily. currently in the process of changing water to get it to 0 without harming my bacteria. i'm also working on changing the feeding amount to see if overfeeding is the cause. oh, and working on fighting back the algae which likes to eat the ammonia and nitrate. oh fun.)
Symptoms and Treatment
How has your betta fish's appearance changed? Has a small bump on the right side of his nose, that includes the nostril and goes up to his eye, but does not seem to affect the eye. The bump has one white spot on it, and his eye has a bit of a white stripe above it, but I am unsure if that is related.
The bump is smooth and is the same color as his skin except for the tiny white spot.
How has your betta fish's behavior changed? No real behavioral change.
When did you start noticing the symptoms? About 2 weeks ago I noticed the bump, it has gotten a little bit bigger since.
Have you started treating your fish? If so, how? At first I thought it could be ich (since he has the history of it), and added 1 drop of Aquarisol and have kept the temperature as close to 78 as possible to see if that was the case. (i understand that it should be 80 to 85, however with the way my house heating is and the lack of a good micro-sized heater, a consistent 78 or higher is difficult to achieve.) I also added a pinch of salt to help healing in case of an injury. I also increased water changes.
After a week of no change, I also added two drops of stress coat plus at the suggestion of my aunt who has worked with aquariums. Now on the third week, there's no change in the bump.
Does your fish have any history of being ill? He had ich when I first got him (almost a year ago). Aquarisol took care of it, and I keep about 1 to 2 drops in the tank most of the time (keeping track of water changes) since I feed him the flash frozen brine shrimp which can carry ich.
He's gotten the normal fin hole or two, but always healed up nicely with a little salt and/or stress coat.
He recently had a little fin rot, but increased water changes and a little salt took care of it.
He's quite a fighter (flares at any new thing that comes near the tank) so maybe this is an infected nose scratch?
Nothing I read about fish diseases and bumps has really described what he has.
Any help is greatly appreciated!
How old is your fish (approximately)? 1 to 1 1/2 years old.
(note:the color is skewed. sorry for bad quality.)
