I've had this betta for about 2 years now when I bought him from a reputible seller that I'd checked out for almost 6 months before buying from. He's been ill a couple times in the past but nothing big; Popeye that cleared up in 3 days, very mild fin rot that cleared up in a week or so, the usual.
On Sep 19th I moved to CA from WA, bringing him with me. I've moved back with my parents, and my father started up a bookcase aquarium for him so by the time I'd get here, everything would be set. We checked the levels of nirates, nitrites, ammonia, and ph and everything was kosher, so we put him in, and for 1 week, no issue.
For the last 2 weeks or so, he's been showing signs of Swim Bladder Disease; hard time swimming; protruding belly; lack of feces and visible bowl movements. So, first thing I did was fasted him for three days, bought a better heater and raised the temperature of the water to about 78-80, and a small water change. after 3 days, I fed him 1 tiny blood worm and 1 tiny bit of green pea. fasted the next day, then the next I fed him 3 small pea bits, then the next day 1 tiny blood worm, and have been switching between blood worms and pea bits the rest of the time, fasting him this last sunday.
He's still struggling to swim after 3 weeks or so, but still shows a healthy appetite. More than anything, he just seems to miserable to me. Thinking the nitrates might be an issue, I just tested the water (last water change 5 days ago) and according to the test he has 0 ppm.
For the record, I've also lowered the water level and added a small floating log for him so he can hide in it and have more access to surface air.
Question; what else could it be? What else do I need to test for? can this be a perminent thing? What else can I do? What is the average life span? (I'd heard 2-4 years and 1-2 years, so I don't quite know anymore).
thank you for your time, sorry if this is a repeat of an earlier thread.
