new betta twitches from time to time?

[dbrooke1]

hello! my new betta named andy lives in a 2.5 gal tank.
temp is 80 degrees. between 78 to 80.
no filter.
no air stone.
it is heated, yes.
he lives by himself.

food?
he eats omega one betta pellets, on occasion frozen blood worm and frozen brine shrimp.
fed him two pellets twice a day, but just cut it down to three pellets total a day.... frozen blood worm and frozen brine shrimp once each so far.
maintenance?
did one 50% yesterday, noticed he was inactive so went ahead and didalso 100% change today. plan to do 100% change twice/wk.
prime water conditioner is used.

water parameters?
water not teste yet. going to see if i could swing by maybe a petco tomorrow
to have a water sample tested.

symptoms and treatment?
from what i can tell, he looks pretty much the same .
his behavior change? maybe 3 days ago while looking at him, he floated near the top of the water, looked at me and his head twiched! idk if its a twich like movement of his head. super fast from side to side. then, today i noticed when
he swimmed he would twitch maybe. like he'd swim and twitch foward real fast. one time, his body went sidways before "twitching" to a normal position if this makes sense. he "never" darts against any objects, only twitches randomly and on occasion.
he floats at the top of the water sometimes and then other times he chases his own reflection or swims around. earlier today he'd hide in between his live plants. was fasting him today. since he was inactive i fed him and he is moving more.
i started noticing his symptoms 3 days ago.
i treated him with a 100% water change.
i got him from petsmart last monday, and he seemed healthy with a good personality.

i believe i pretty much explained it above. any input is welcome please. thanks!!

I don't have an answer for you sorry, but I'm posting so it will go back to the top.

thank you.

I am by no means an expert on this, so wait for others to weigh in, but it sounds like fairly normal behaviour to me. If I'm visualizing correctly what you are describing, my betta, Fluffy, does this, too, and it looks to me like interaction not spasm -- kind of how a puppy will do a playful lunge or sideways motion.

i hope you are right. :) if it's true it would make sense because everything else about him seems normal. it's good to hear your fish "may" be doing the same thing.
looking forward to seeing what other people think as well.

okay, i'm almost 100% convinced that his behavior is not normal. he definately twitches. i looked up "twitching betta" on youtube and found another fish who seems to do just what mine does. i'll post up the address of the video to show.
the last week or so his twitching behavior seems more frequent and slightly more noticeable or apparent.
the color around his head became a slightly darker shade. hmm? and the little, clear fins on his side (what are they called, ha?) has a red color on his body near them. it almost looks like a cut on both sides at the base of those fins. i'm unsure if they also indicate something is not right?
i don't have a clue what could be cause of his twitching. help, lol? :(

on youtube the title of this video is called
"eclipse twitching".
will copy and paste the address tomorrow.
this is not mine, it's somebody else's fish. although my little guy started twitching like this fish in the video. although, my andy's twitching seems bigger.
now, when he's not hiding in his cave except to go to the surface to breathe air (poor thing...) he periodically twitches when he swims. it's very obvious. and he swims faster than he did before in his little tank.
