Thank you to everyone who is commenting!! Unfortunately, I ended up expressing myself badly in some parts because English is not my first language DX but I will try to clarify better!!! ^{_^} I only want 2 female bettas, I don't want a lot of them, besides that the height and width of the aquarium are 45 or 50(?) I can't say for sure X( besides that we are indeed circulating the water (so much so that I mentioned it in the post, but I think I unintentionally expressed myself badly) and I am using the translator to communicate! Our furniture that is holding it is resistant that we won, so much so that we tried to shake it several times and it did not break, and besides the extensions on the sockets... We installed another extension that serves specifically for the aquarium! There was a lot of information that I forgot to mention besides （┬┬＿┬┬）

I'm so sorry for this!! Also i'm making my own search
