Okay, so here's the deal: I bought a 10 gallon and divided it up three ways using the binder/plastic canvas to be the future home to my three VTs (1 female, 2 males). The dividers were siliconed in, and I started to cycle the tank. My problem is I don't think two out of three fish will be happy with it. Wanda is entirely too energetic for something tall and narrow. Otto flares at anything, and I mean anything. He's been known to flare at a hair tie of all things!
So the new plan is to divide the 10 gallon 60-40ish and put Hector, my king betta on the bigger side and Perseus, my other VT on the smaller side. Both bettas are pretty easy going and I think would make good neighbors. I'm pretty sure I can get the silicone off without any problems, but I want to know if there's anyway make/buy a sturdy divider without silicone. The tank is halfway through its cycle so I'd rather not drain it. Again, I think these two boys will make good neighbors, but Hector is about twice Percy's size so any divider does need to be strong. Any ideas?
