Each of them are a little less then an inch long and I have them currenlty in a 6 gallon holding tank until I get my 26 gallon long tank up tomorrow.
They are the only occupants. Live plants, cave, clay pot. Tank has been up and running for over 1.5 years.
I just moved the more aggressive one to my 45 gallon community tank and she is happy as a clam.
I realize the 6 gallon is way too small for everything but a single betta, but it was only a temporay situation and since I thought they were pretty peaceful fish, I thought it would be ok. Ooooops, my mistake.
