Is it possible some betta's dont like larger tanks

[ral]

A few weeks back we got 3 female betta's

One when to me, the other to my GF and the last to her sister.

I placed mine (her name was Sam) in a 2.5G planted tank.

Two two others were placed in a 15G tank. The two females did not get along and the larger one would bully the smaller one, so the smaller one went to a 1G jar. The larger (my GF's) one died 3-4 days after we brougth her home.

My female was not eating but seemed healty enough so I gave her to my GF to replace the one she lost. She was placed in the 1G jar. The girl in the 1G jar moved up to a 2.5G filter tank (corner filter).

I just learned she died yesterday. One week after moving up to the 2.5G tank, the girl died.

Only Sam is left.

from what I'm starting to pick up on with Betta's is when you put them somewhere leave them there, my female Betta was healthy when i had her in a 10 gallon and i moved her to my 67 gallon and she got sick i had 2 in my 67 and when i decided to make my empty 32 into a female community i took the lone one from the 67 and put it in the 32 and she died not too long after

Sounds to me like the deaths have nothing to do with the size of the tanks.

Could be. I have purchased 4 Betta's in the past five weeks. Three "Betta's in a cup" and one from a breeder.

Together with my GF and her sister we have pruchased another 9 betta's. Seven "Betta's in a cup" and two from a breeder.

So far, none of those from the breeder have died. Of the ones bought at the lfs, 3 out of 10 have died so far. Two died within 2-4 days from purchase.

None of mine had died but one had Ich and the other had finrot.

Maybe, it just that they are kept in small disposable plastic cups which adversly affects its health.

The bettas just got sick. Maybe it was starting when you got them. The size of the tank doesn't matter. I've even heard that you can't put bettas in very large tanks. What a load of manure that is. Some think since they CAN live in a mud puddle, you need to keep them in a small dirty cup. Every betta I've ever put in a large community tank thrives. They hold better weight, have better color, and seem a lot more happier than in a smaller tank. I even kept my best male in my 55 gal by himself before some fry were big enough to use it. He loved it. He swam back and forth. He would folow me from one end to the other at times, watching me do water changes on other tanks. Every tank carries bacteria that cause diseases. The fish get the disease when they start stressing. They either stress from the shipping, laying in a cup for days, ammonia buildup in a tank, or something happening to the fish. The stress lowers the immune system, and the disease can start. This is the reason for quarantining a new fish in a hospital tank for 2 weeks. When you know for sure it has not started to get sick, introduce it to your permanent tank.

i agree. My betta is doing great in my 10 gallon.
