My beta, Seuss, likes to scare me and act like he's dying occasionally, (like for a week or two,) then overnight gets better, but this time, i really think something is seriously wrong with my baby.
He's in a 2.5 gal tank that gets weekly partial water changes, has a mini hydor heater (water stays about 80 during the day and 76-78 at night,) a 1-3 gal Whisper filter and i use Aqueon Betta Bowl Plus water conditioner/ dechlorinator. He's only had a filter for a few months, before he was in a 1 gal bowl with the heater untill the bowl broke and gave me an excuse for a bigger tank. : )
He's been less and less active, but i have no clue how old he is since i got him a year ago from a friend who got him from a friend. But for maybe 2 weeks, i've noticed the end of his tail (he is red with blue highlights on his fins, and silver on his gills; i will try to get a pic up with this post,) is getting darker and turning extremly dark red, while his chin and forehead seem to be getting lighter in color. he also has two rips (one small, one larger,) in his tail, possible from some plastic plants in his tank. For the past week or so, he has started spending all day in either a dark corner of his tank or hidden in his cave with his body curled around in a C shape. Once i get his attention, he'll gladly eat and flare up at a mirror, but then he ends up back in his corner curled up. I also just noticed this morning that his abdomen area seems to be getting slightly bloated.
The food i had for him was getting old, so maybe that's the problem? i finally got out and bought him new food. (HBH Betta Color Bright) but will try fasting him for a few days and see what happens. Also, when i cleaned his tank the other day, i didn't notice as much poop as usual.
Any help anyone can give me would be great. I accidentally killed my last betta because of my own laziness, and I WILL NOT kill this guy!!
i'm still learning and have considered using aquarium salt, but am afraid to hurt him. Thank you guys so much for any help you can be!
