Multi-sectional Betta Tank

i think that is surprisingly very neat looking! i would get like 80 dollar bettas from a farm and stock them each in those... would look incredible! i would say 5 gals minimum for each section and i dk about the filter

please do updates if you do it!

might want to put a black backing on the dividers to keep agression minimal and put a female in the fron of the flow so her hormones would get the males ready.. Also add some riccia or other floating type plant to serve as an anchor for bubble nests

Prbably have 2.5 gallons per section minimal, and maybe use a canister filter instead of a UG unless you have it reverse flow

5 gallons per section, minimum.

i wouldnt do a big undergravel filter

if each section is separated by glass, you'll probably have to rig some filtration setup where there are separate intakes and outputs all going to and coming from a master canister filter. or, you could have independent filters for each section.

if each is separated by mesh, then you could probably get away with one big filter, albeit with a diffused output and intake to one betta at either end isnt swamped with a huge flow. that said, you'll probably end up with something similar to the above.

i would like to add the fact this is very very neat looking but idk how this would work out IMO like the undergravel filter would possibly work i think

Maybe a canister filter with the intake and output at opposite ends. water over flows from one section to another. from my understanding, bettas dont like a lot of water movement

No idea about filtration, but that setup looks sweet!

I would add some sort of floating plants to each division. Balance it out nicely.

Also, not a big thing, but the white really clashes with the black. If you could you should consider painting the stand.

Absolutely beautiful! I did several 20 g long and some 10 g tanks the same way a year ago or so. For the 10 g tanks I made just a slice in the mesh so I could use 1 filter and the outflow went to both sides. If it were me I'd go with an UGF for the tanks pictured. Man, they're awesome looking. Oh, and I had the white mesh and the boys didn't seem to notice or be bothered by their next-door males at all. 5 g minimum is a good size. I also put 3-4 Cardinals in each Betta section. In hindsight I'd have added 3-4 Pygmy Corys. Not sure how Pygmy Corys would do in a set up like what's pictured if it had an UGF though. They prefer more water flow than that.
