Betta acting strange

[Silverfang]

Just got home after being away for two months, and I've noticed my betta doesn't look quite the same, and he's acting strange (from what I remember). My mother has been taking care of him, so don't know if he's just being sulky or if there is something really wrong. I'm going to the pet store tomorrow, and he's due for his full change.

I discovered that mother has removed a big piece of his silk plant, so I'll be getting a fuller one to add, going to re-arrange his decor, smaller decoration, another plant (silk). I have a smaller tank .8Gal I can use to QT him with. Thinking I should do a week of this for daily changes, his fins look like they could use a boost as well.

Going to see about uploading some pics I got of him.

Symptoms and Treatment
How has your betta fish's appearance changed?
He's super clamped, stress striped, the end of his tail is shorter, but I'm pretty sure it's from a bout of fin chewing. His body looks a little off, so I'm not sure if he's slightly bloated, or if the rest of his body is just smaller.
His eyes look different, almost like they've been tinted.
How has your betta fish's behavior changed?
He just stops and hangs motionless at the top of the water, fins not moving.
When did you start noticing the symptoms?
Have you started treating your fish? If so, how?
Not yet, will be doing a full change tomorrow
Does your fish have any history of being ill?
Just fin biting
How old is your fish (approximately)?
Got him in Feb

Aw, I hope it's just something that clean water will help solve!! Best of luck!

Did your mom happen to mention what the water change schedule was? :/ Is this Scuzi who is acting funny?

My best recommendation is fast him for a day in case she overfed him once or twice and then get him into epsom salt. Start with 1 tsp and see if that helps with his size at all. If even a few days of clean water doesn't help, I'd up the epsom salt to 2 tsps. Watch for abnormal poops in case he's picked up an internal parasite. Also, if you can, look for Jungle Labs Anti-Parasite Medicated Pellets. If he'll eat, feeding him those in garlic juice would help him fight off any parasitic or bacterial infection he might have.

I hope he feels better really soon and I'll check in with you often. Good luck!

Yes it is my unholy terror Scuzi. She's being giving him two changes a week, she complained to me enough times about it. Unfortuntely mother has very poor eyesight, I mean really bad, so she might not have noticed if he went through any changes. She wasn't quite sure if he had bitten his tail, but it looks shorter than I recall. I was thinking of picking up some frozen daphnia or another new kind of frozen food to give him a bit more variety. Maybe frozen brine shrimp?

[Sakura8]

Brine shrimp is easier to feed than daphnia and it has a similar laxative effect. Maybe not as pronounced as daphnia but it does help them go. Daphnia is so small you have to feed it with an eyedropper.

I understand, my mom has very, very bad eyesight too. Most of the time she can't see my fish even with her reading glasses on. Two changes a week in a 2.5g should have been fine, that should have kept the water free from ammonia so I don't think it's ammonia poisoning. Hmm.

[Silverfang]

I'm wondering if it's more stress/ him being moody.

[Sakura8]

It could be. Did he tend to be moody before?

[Silverfang]

VERY! And I mean very.

[Sakura8]

Haha, somehow I'm not surprised. Not if he had a habit of tailbiting. Well, I hope he has a moodswing soon and unclamps for you. Maybe he really missed you and he doesn't quite realize you're back.

He's still acting clamped and sulky. I couldn't find another kind of pellet that would have sufficient protein while out, did pick up some frozen brine shrimp. He's in a bare bottom .8 gal tank so I can observe him for the next week. He's got his heater, thermometer, and two anubis plants floating in there. I sure hope he perks up, he looks so sad right now.
Bought him a new tank for after quarantine, one that's not so high, and a few pieces of new decor, a squishy feeling rubbery plant and a betta log. Maybe a couple days with daily water changes will perk him up, then I'll introduce him to his new home.
