Hey there new here ;) and pretty new to taking care of fish too
So I have a betta in a temporary 1gallon and wanted to know what is the minimum tank size and if it's possible to have a swordfish a betta and maybe some neon tettra? Or another "School fish" (I think that's how you call fish that live in groups)
Thanks in advance and sorry for any english mistake
If swordtail and small shoal of schooling fish was my aim along with a betta, I would be looking for a minimum 20 gal long tank.
I say 20 gal long ,because swordtails are active swimmers and need the extra room to swim that a long tank provides.
If it were just a betta and a small school of tetras, then a ten gal tank with heater and filter would in my view be the minimum.
The most important medication in your fish medicine cabinet is.. Clean water.
they will only get along if the betta has enough room to stake its' territory and is very calm to other fish. I agree on having a minimum of 20 if you want a school fish, betta and swordfish. if it is just the sword fish and betta i think 15 gal would be best. but i am very cautious about overcrowding.
