Hi all! So, just to give some background, I have this dream fish room that I'm currently planning. It's not going to be a reality for some years yet (I need to get a house and such first because this is going to be a pretty much permanent fixture) but I'm planning for it now so that, when the time comes, I can jump straight to it.
Basically, this will be a display fish room, so I'm trying to keep things looking aesthetically pleasing while still accommodating the fish. If the exact idea becomes a reality, the room itself is going to be either Atlantis or Nautilus sub (from 20,000 Leagues Under the Sea) themed with steampunk undercurrents. I want the only lighting for the room to be from the fish tanks and maybe some blue ripple lights on the ceilings with no windows so when you step into it it literally looks like you just stepped into an underwater world.
Now, as bettas are my favourite fish, I really want to have a "betta wall" be part of this setup. My current plan is to build three-layer stands on three of the walls with custom-built acrylic tanks (which I'm looking into building myself because in the long run I feel it'll be a ton cheaper and I can customize them to my specifications).
Basically, picture your typical Petco tank setup, but with larger tanks and better care as these are going to be permanent homes rather than temporary holding tanks.
Now, on to the actual question.
For the bettas, my current plan is to create large tanks and then divide them so that each betta will get roughly 5 gallons of space to himself. Some of these bettas will be my pets, of course, but a friend and myself are also looking into hopefully starting a betta rescue sometime in the future, so these tanks may also hopefully hold fully recovered individuals ready to find their forever homes.
However, what are the issues some people have encountered with divided tanks? I know falling dividers and jumping are some (which is why these dividers are going to be siliconed in place and well above the water line as they are going to be custom made for bettas), but has there ever been issues with a disease outbreak wiping out the entire divided tank despite adequate quarantining? That's the main thing I'm concerned about seeing ideally there will be maybe two large tanks per row to a wall (so six tanks to this wall, and depending on the size of the wall available there may be up to 10 compartments if we say each tank is roughly a 55g -- though seeing I'd be custom making these for bettas they'd probably be a lot longer with less height), with these tanks divided and connected to cut down on heating and filtration costs (which, with a ton of individual heaters, would probably get super expensive as far as electricity... with that rough estimate I'd need about 60 heaters), with a central airline and large pump powering multiple sponge filters.
Ideally, these tanks would just be separated completely, but with the cost of heating (and the fact that I can't just keep the room 80F constantly) that's just likely not possible. Not to mention how many outlets I'd need.
Basically, I suppose these would be suped-up betta barracks to be honest. Except each compartment would have substrate and be fully planted like mini display tanks.
Would there be any alternatives I could possibly look in to that would still save energy-wise, or will proper quarantining and quick removal to a quarantine tank if necessary prevent any full barrack crashes? I know stress could possibly be an issue because the males could see each other, but I'm considering blacking out the dividers themselves and cutting slits for water flow so that the males can't see each other.
