I just put my male betta in a five gallon tank (was in a one gallon) after school today i went upstaris and i looked in there and he build a buble nest
Awe thats great !
I was really happy when i saw my first bubble nest too
You will see what a difference putting him in a bigger tank will make to him swimming around and to you as far as watching him in an aesthetic manner.
I personally wont ever put a betta in a small tank now that i have moved mine in 4.5 gallons i get so much pleasure out of watching them and their beautiful tails..
