as some of you may know i bought a small blue betta 5 days ago now i named Bluey because he is blue and because he looked blue in his very dirty cup. (Heres the thread http://www.bettafish.com/showthread.php?t=110364
) he is very small, hes not fully groan and he is skinny.
He is currently in a 1 gallon unfiltered but heated tank because i had no where else for him and he is soo small i thought it would be better for him. he eats fine and swims around a lot now. still sit at the bottom from time to time to rest I assume. My plan for him is to get another 10 gallon and divide it and put him on the side that has no filter. when can i do this? should i let him grow more in the 1 gallon or can i upgrade anytime? I want to buy the tank tomorrow cause i will have the money but it doesnt mean i have to set it up right away?
