Story time about rescued betta

So my friend had this betta for about 2 years now and wanted to get rid of him but couldn't because no one would take him. I would have earlier but I had no room and already had a betta who I named Marvin, who recently died . BUT I guess In a way it was a good thing because I got this guy.(still trying to figure out a name for him though) but anyway he was living in a little one gallon bowl with 3 Minos. She feed him about once a week and I only ever saw him at the bottom of the bowl kinda just laying there. But anyway I took him and put him in my 5 gallon tank and within 2 hours he was already swimming all around and seemed happy! I've had him in there about 3 days now and he's already made a bubble nest! I only feed him about every other day so far just to slowly try to introduce him to food everyday not just once a week. He seems to be doing great! So I hope it stays that way lol. Just thought I'd share this story on here though. I'm not sure what type he is exactly but he's pretty big, he is like twice the size my old betta used to be who I fed regularly! Haha
Some pictures

 

Handsome guy

 

Looks like he has some fin rot, daily water changes should clear it up
He's beautiful! By his looks I'm guessing a Delta or HM tail type. How big is he(body wise)?
I'm sure he's loving the new space!

 

Beautiful! I bet he's really happy with the change in his fortunes

Yes I noticed that two I've been working on the water changes but I was wondering since she had him so long and I don't know how long his fin has been like that if it will actually heal back. And I'm not really sure haha I don't really know how to measure him because he moves to much

Also with the fun rot I was wondering if it could have been the Minos nipping at him. They seemed to scare him to the bottom of the bowl and not move much. I'm also assuming that you mean the two front fins that help him swim Because that's the only place I can see, but I also might be missing it if it's on his tail. But also if we are talking about the front fins is it possible that the Minos were nipping at him or is it definitely fun rot?

 

It should grow back, it might take a while but it is definitely possible.
He definitely has fin rot on all his fins, the minnows most likely played a part in it, that and the bad water quality.

 

Frequent water changes and quality, high protein foods will help

Should I be feeding him more then? I'm worried about over feeding him and making him sick or something, but he never seems to be done he always seems like he wants more. I'm not sure about the protein though it's aqueon betta food it says it's all natural

Thank you for all your help!! And oh my I was spelling minnows wrong the whole time

 

It's OK, but there are better foods out there. You can offer bloodworms, brine shrimp, human-grade shrimp (I shave small portions off frozen ones), mosquito larvae or better quality prepared foods like Omega One.

 

I don't want to hijack this thread at all, but Aquaphobia , small question! One of my bettas completely turns his nose up at bloodworms and brine shrimp, won't even touch them. He will literally only eat fish flakes lol. Is there anything else I can try to help provide more protein? I don't know where to get mosquito larvae.

 

Put a bucket of water outside and wait! If you've got any mosquitoes in the area at all the females will see it and lay their floating egg masses (called "rafts") from which will hatch the larvae. Check the legality in your area though. Due to illnesses borne by adult female mosquitoes there may be a ban on standing water

 

Update: there improvment!! His two front fins aren't really healing much (or just slower) but he's definitely looking better!
