Symptoms and Treatment
How old is your fish (approximately)? Between 2-3 years. I wasn't the original owner, so I don't know for sure.
How has your betta fish's appearance changed? He looks mostly the same, but his fins look a bit ragged. They used to have a very smooth, symmetrical shape, but now they look uneven. His right fin also appears to have a tiny hole in it, but I'm unsure if it's really a hole or just the way his fins split off. However, I never noticed it before now. He is a red fish, so that makes it difficult to tell if he's actually injured.
How has your betta fish's behavior changed? Enjorlas (Enjy) keeps lying at the bottom of the bowl. If I get near him, he swims over to me. When I put my finger up to his face he swims backwards as fast as possible, but if I put my finger an inch or so away from him he swims directly towards it. He's still eating very well. He's blowing bubbles, but not nearly as many as he was.
When did you start noticing the symptoms?
Roughly a week ago. I've only just noticed the ragged fins in the past few days.
Have you started treating your fish? If so, how?
No. I'm not sure what's wrong with him, or if anything is at all.
Does your fish have any history of being ill?
Not that I'm aware of.
A few other things:
I recently moved. During the move, the fish travelled in the car and stayed in hotel rooms. It seemed like they were fine with it, except that I had to take the heater out during car travel. Now I'm in a different state, which means I've been using different water to fill up their bowl with. I've been generous with the condition and tried to only do partial water changes the first three weeks because I didn't want to upset their systems. I keep the fish in my dorm room, which is often dark because I'm not in during the day. I've almost wondered if the darkness is making Enjy think he should "sleep" more and made him lethargic. The bowl is on a shelf with a few other items. I didn't know if the lack of a view would upset either fish at all. Javert (the other betta in the bowl) is extremely happy and content, but Enjy seems very letharic. I've considered the possibility of fin rot, but if it is, it's too early on to know for sure, I think. What's wrong with him? What should I do?
