I have five nerite snails, two mystery snails 10 ember tetras and a Betta in a. 10 gallon. Aquadvisor says I’m 90 percent stocked. With just the Betta and the embers I’m 60 percent. I was thinking of rehoming some snails and then putting up a divider and getting another Betta. The divider has holes large enough for the ember tetras to swim through and enjoy the whole tank. Aquadvisor says I’d also be 90 percent stocked with that combo without snails. Is this sight accurate? Not sure if my current Betta will be depressed if he’s used to the 10 gallon but I really would like to save another Betta fish. Also, what bubble filter can anyone recommend for a 10 gallon? My tanks is heavily planted
