So today I went to Petco to get some cuttlebones and long story short, I came out with a new rescue. I haven't gotten a new rescue in quite a while so I was hoping you guys can give me some quick advice. Sorry that this is so long but please give advice if you can.
First, I know how to acclimate after a water change but for a new rescue I know you have to do it a lot longer. Can someone give me more specific instructions?
Second, should I try and feed him so soon? And how much should I try to feed him if he'll eat? Last December when I got my last rescue I called my Petco to ask how much they feed their bettas because I didn't want to stuff him and I was told they fed them "a pinch and a half every other day". I normally feed my bettas 8 Hikari pellets everyday. How much should I feed him now and how do I adjust him to eating more long term?
Lastly, except for warm water, what else should I do for him? Since he's been in the ammonia filled cup should I change him water more often for a while? Should I cover his tank with a towel?
Here are some pictures of him. He's kinda active but he does lay there some. He has perked up a bit since I've gotten home. I wasn't planning to get a new betta so I need to clean his new tank. Should I try to float him in one of my other tanks? I've heard of doing that but my other boys flare a lot so I'm worried they would freak him out. Thanks for any help!
