Smallest Tank Size

[fluffycabbage]

What is the smallest suitable size for a single betta? 40l or so? Im going to be putting my tetras into the main tank soon, and our new betta Blueberry wont need 90l all to himself! Im going to be using that as a cory breeding tank.
Or can i combine the two? Could a betta be trusted with baby corys?

Smallest I would ever go is 17L.
It all depends on Blueberry, if he's peaceful give it a try, but I would personally not risk it if you are wanting to seriously breed corys.

Smallest I would ever go is 2.5 gallons.

My LFS think a large cup (around 1 litre) is OK for a betta

yep seen plenty of those half the size round ere

Blueberry is pretty active, very different to my last betta! God 19l? Seems a bit small

Well you said minimum...
Simon is in a 17L cube tank, he absolutely loves it. I had him in a 64L before but he just sulked for a week and refused to come out, I think he feels more secure in his own tank.
He get's lots of exercise by swimming into the filter outlet of 200lph.
He loves a current.

Smallest I keep them in is a 2.5 gallon. This is the smallest tank I have available. Breeders raise & keep show winning bettas in 1/2 gallon or less on a regular basis, though this requires attention to water quality. Where I to consider breeding splendens the 1/2 to 1 gallon jars would be an item I'd be getting in.

My LFS thinks that a small cup (around 1/4 litre) is OK for a betta

One gallon is the minimun IMO for a betta. Anything bigger is welcomed

Ok thanks everyone for your input

I honestly don't think anything less than 5 gallons (19L) is suitable for a betta. I've kept them in smaller and they just don't show their personalities as well when they're in smaller tanks. Also, smaller tanks are MUCH harder to maintain the water quality in, as well as more difficult to keep the temperature steady (not that many good adjustable heaters made for tanks under 5 gallons). Right now I have one male in a 10 gallon tank (all by his lonesome), one in a 9 gallon tank, and two in a divided 10 gallon tank (so they have 5 gallons each). My two females are in my 55gal tank.

3 Uk gallons but the smallest is enough water for them to be covered. I have been to the thai breeding factories and seen them in that much water and still breeding.

I was looking at a tank around the 30-35l mark (10ish gallons?), so i guess im ok then

A 10 gal would be great for him

Yes, but that's for breeding. If you research when and in what conditions bettas breed, they breed right before monsoon season when the water levels are the lowest in their natural habitats. If you have the water level deeper than a few inches, they're less likely to breed because the conditions aren't right. Generally speaking, though, their natural habitat is relatively shallow pools (nothing deeper than 18" as their swim bladder is not designed to cope with the higher water pressure found in deeper water)...not puddles, which is what "enough water for them to be covered" equates to.
