So I see some great tanks just maxed out with acros. How do I know which ones can touch each other without killing of one another or am I not looking at your tanks right and their not touching . Just looks to me that its super crowded in some of the tanks I see ? I like the look and Im not at that place yet where I need to worry about it . I just was wondering so when the time comes Ill know what to do ?:bounce1:
