Thanks tancho for your comments. quality of the things(filter, medication and food) I use are good and expensive ones so it is worth. Dreamed about keep good aro for a long time so maybe it will come true soon. Trying to be mainstream aro hobbyist I suppose.

My main worry is if the 1.5, green and rtg(not yet buy) get bigger and fight. I have to separate them, I need to get 2 more tanks. No space in my home.

Do you u think that this won't happen? Other comments are welcome.
