Thanks for all your responses. I am only 16 and you may not understand this but I get bored with fish after awhile. i didnt really word that right but its like, i like getting new fish alot. and i have 3 nice LFS' around me that will and have taken fish from me before so it will be no problem when it reaches to big for my 90 gallon. i would put it in my 20 or 20 gallon long until it got to be 4'' or so, then move it to the 90.
