So I moved everyone from my five gal to my 20 gal! Everything is going great except I don't think my betta, Suede is too happy about it. I think the filter is too strong for him and all the activity is stressing him out. Also upon learning he and my oto's aren't temperature compatible I decided moving him back to a five gal would be the best decision. He still eats fine, and he looks rather healthy but he's much more lethargic and lays on his log most of the time. Could I possibly do a quick transfer to make sure he doesn't start doing worse, if so what would you recommend ?
