Today I signed up for this website, knowing that after work I would be on my way to pick up a betta fish and give it a good home. I'm a little worried that my first post here is in the diseases and emergencies section, but hopefully you guys can help me.
I haven't owned betta fish since I was like ... 10 and my mom took care of them. But I did a LOT of research before I got one (as I do before I get any sort of pet.) and today I was on my way to the pet store to get a fish. It was a specialty store, that had a lot of exotic fish and the staff seemed very knowledgeable about all the fish in the store.
Except the bettas. They had a dozen or so jars set up near the front with the bettas, and we picked two. One was very lively and yellow, we named him Bumblebee. The other was red and blue, we named him Optimus Prime.
Bumblebee seemed very healthy and lively in his cup. He was swimming around and being very active. But he has some black spots on his scales I'm a little worried about, they don't look too abnormal, but I don't want to let anything go unchecked, yanno?
Here are some pictures:
Optimus on the other hand, was really calm and didn't move to much. I think this is from the stress of moving around and going from a bag to a big bowl and whatnot. He was fully acclimated to his bag over a span of about seven hours, because the PH wasn't much different for the water. He's swimming around and being quite active at the moment, but as you can see his fins are slightly crooked, and I'm a little worried about it. Actually, one of the main reasons I got him were because of his awkward fins, I was afraid that nobody would want to buy him because of an athestic deformity, and that he would sit there forever. His swimming is straight for the most part, but sometimes he kinda swims to the side a little bit.
Are these little things normal for betta fish? If not, what can I do to help get rid of it, or make it not get worse?
