Now before we get started, I know that one gallon isn't enough water to support a cycle, builds ammonia far too fast and and would need a lot of work to be viable. Under normal circumstances, I would never advise anyone to place a betta in a container under 2 gallons!
But I know there are people who have figured out how to do it right! I have a single female in my sorority who is not very good with groups. She stresses easy and hides all the time, to the point that finding her at feeding time has become a frightening experience. I always worry she's dead. Her favorite hiding place is a hole in a piece of driftwood, and the first time I saw her in it I thought she was dead. That was a huge stress! Now I have decided that she would do better in her own small tank with lots and lots of hiding places. This is simple, I have a couple of 2 and 3 gallon tanks sitting around. Sh can be moved at any time.
But this made me consider the possibility of a one gallon tank. I have a very beautiful bowl with spirals on the top and bottom and I have always wished I could plant it and add a betta. The girly fish in question is a very small thing, smallest one I have, tail and all she is less then an inch. She prefers the heavily planted areas of the 29 gallon she's in. I thought a heavily planted one gallon might work, and I would love the challenge it would bring!
Now I just need to get some information, and I'm curious if anyone here has ever had a planted a functional, humane, one gallon tank or something similar. Please, any advice would be great.
For now, Rosie, the girl who's having the problems, is going into a 3 gallon with a few extra plants so she has lots of hiding places.
