Hi everyone. I am hoping for some assistance in pinpointing exactly the cause of my betta's apparently lack of wellbeing. The spots seem too big to be Ich to me, and not the proper shape to be a fungus (going by the pictures I have seen). I suppose it's possible he's changing colors... Or maybe it is something I just don't have the skill to identify properly...
It's hard for me to know for sure he even is sick, as I just recently got him from a local store here. I have noticed he seems very lethargic, though, the last few days. Mostly stays at the bottom of his tank and comes up for air quickly then returns every few minutes. He stills seems to have an appetite but he does spit the food out instantly after he eats it. He's been doing this since I got him, and I assumed he was trying to break the flakes up into smaller pieces, since he usually will try to eat the broken down bits after he spits them out.
This betta whom I have named Dorian is supposedly a crowntail, although frankly now that I've seen pictures of crowntails I have my doubts he actually is. Regardless, I'd like him to have a chance, so please tell me what you think may be wrong with him. He lives in a 5 gallon tank that is heated by himself.
I may have been overfeeding him... Possibly by quite a bit, as the instructions on his BettaMin flakes are really very unclear. It says to feed him 2-4 times a day as much as he will eat in "several minutes". It seemed like a huge amount to me, but he was eating it, so I kept feeding him. The last few days I've tried nearly cutting all his food and feeding him a pea, which he seems to have eaten over a couple days. Still he doesn't seem quite right.
In summary, I'm hoping the picture will reveal the possible issue. In addition to the picture:
- he stays low in the tank 90% of the day, just coming up for air
- he's developing strange light blotches around his head and neck
- he's turning a silvery color at the back (not sure if that's an issue)
- very unactive
He resides in:
- 5 gallon tank
- filled with bottled water (uncycled)
It might be relevant also to mention that a thermometer I had just attached to the side of his tank shattered with nearly no pressure on it from my hand and spilled it's contents into the tank with him. Several shards of glass, small metal balls and red liquid were left at the bottom and he swam right at it. I bought this at a large chain store that will remain nameless but is big on creating an empire of cheap imports and low prices. I did a full tank change which was probably unnecessary but I didn't know what was in that thing, and this is around the time his health seemed to decline. I'm not sure if that is related, however, as he wasn't in the best health to begin with to be honest, but he at least was swimming around normally.
Thanks for any suggestions or advice.
