Congrats on your new family member. Rosenbaum is extremely handsome. I hope Mr Smol doesn't get jealous of having to share his Mum. I hope you'll share regular pics of Rosenbaum as well as your updates of Smols antics. (Speaking of which, I'm having Smol withdrawals. I've missed seeing his photos).
While betta can live in small containers, it is really best to give them a larger tank.
Betta like to exercise and larger tanks allows them to do so.
It’s not only better for their health to get activity, but a larger fish tank means a better quality of water too as smaller fish tanks can quickly become soiled and filled with other contaminants.
Just iike with a budgie cage, I recommend you get a wider tank rather than a taller one.
A betta fish tank should be a minimum of one gallon, but ideally two gallons or more.
Rosenbaum is a beautiful Betta! Isn’t he a fantail mutation? Just lovely !
He is definitely a spoiled betta . Actually, a properly kept one! As you know, just because they are a species that can survive in a little cup, doesn’t mean they don’t deserve a healthy aquarium environment. I used to love fish keeping. Thank you for sharing!
You know his mutation is a little hard to tell, I'm part of a Betta forum and they said he's either a delta tail or half moon. He isn't very aggressive, I haven't been able to get him to fully flare his operculum. But he fares his caudal a lot, and it might be half moon? The betta people over at the forum say if it's a perfect half circle shape it makes him a halfmoon. Otherwise he's a delta. Again since I can't seem to get him to fully flare I'm not sure if his finnage is in full display.
He is so pretty though and I'm so happy I'm finally able to give my betta a proper happy life! When I was young I had bettas, but since my parents would buy them and since it was thought that they preferred small spaces, they only had half gallon to one gallon tanks without filters or heaters. But now I can fully spoil this little fish!
